by DJ Short (01 Sept, 1999) An educated and descerning palate is a key requirement in breeding and appreciating cannabis.

An educated palate

The breeding and production of fine quality cannabis is more an art than a science. A creative mind and sense of imagination is necessary to achieve success in this field. The other requirement is a very discerning palate, including the ability to discern and appreciate subtle variations in taste, smell and mental experience.

Anatomically, the palate is located between the roof of the mouth and the nasal passages. The intricacies of taste and palate are complex and poorly understood. The taste buds in the tongue and mouth make up only a small fraction of the mechanisms used to interpret taste and smell.

Olfaction is the term used to describe the sense of smell. The olfactory bulb is the main sensor used to experience and interpret smells. This organ is located behind the nasal passages – up your nose. The sense of smell is one of the most complex we possess, and more of the brain is dedicated to processing smells than any other sense. Smell is closely related to memory, especially older memories. Anatomically, this region is located between the cortex and the occipital lobes, above and around the ears to the top of the head.

Research and experience suggest that some people have a greater natural ability to discern taste and smell than others. The palate can also be developed, educated and refined.

There are many similarities between the wine industry and the cannabis industry. One of these is that both use "expert palates" to identify and discern the various desirable traits of a product. However, unlike wine, cannabis has another added aspect to consider: the type of experience produced by the product. Alcohol's main experience is similar (and overconsumption can be fatal) while cannabis provides a wide range of effects and is non-toxic.

Some herb is strictly pleasing to the mental palate but is not so tasty, while other might taste great but have mild or unpleasant effects.

Spectrums of experience

The first spectrum to consider is the "up and down" experience. "Up" refers to the stimulating aspects of cannabis, while "down" refers to sedative qualities. Up pot tends to liven the disposition and stimulate the emotions, inspiring sociability and talkativeness. Down pot tends to produce sedative and depressant effects. Some people refer to stimulating pot as being a "head" high and sedative pot as being a "body" high, yet although partially true this is also misleading.

Body and head highs are the next spectrum of the cannabis experience. Generally speaking, head highs are stimulating and body highs are sedative, but not all are. Some body highs are stimulating and some head highs are depressing. I once sampled a terribly paranoia-inducing head pot that inspired great couch lock qualities. I called it Boo-Goo.

Early to late harvest will affect the head to body spectrum expressed by a certain plant, with the later harvest tending to produce more body and sedative effects. However, I believe that certain aspects of this spectrum to be genetically inherited.

Next to consider are aspects of duration. Some cannabis tends to be short-acting (15-30min) whereas other varieties last much longer (6-7 hours). Once again production, harvesting and curing techniques can influence aspects of this spectrum, but much of this effect is inherited.

For me, the most important aspect of the cannabis experience to consider is tolerance. This refers to the product's ability to provide the same experience via the same amount over time – the burnout factor. By "over time" I mean the long run: months, years, decades...

Most of the cannabis I see on the market today has a terrible tolerance factor – a quick burnout time with the product's novelty lasting less than a week. Luther Burbank's model of breeding needs to be employed here and no expression of tolerance to your product is to be tolerated. An example of where intolerance to tolerance is tolerated – enough already!

Another aspect of tolerance is "ceiling." This refers to how high (or far) one is capable of going with the variety. How many hits can you consume until more hits are unnoticeable? Most indicas have a low ceiling of less than 10 hits. For me that's usually around 5 hits in one smoking session. If I smoke more than 5 hits of a strong indica I will either not notice the post-ceiling hits, or I will fall asleep.

Some sativas have a very high ceiling, or seem to have none at all! This means that the more you consume, the higher and further you go. Oaxaca Highland Gold, Black Magic African, and Highland Thai were some of the herbs I've tried with very high or no ceiling.

The final aspect of mental effects to consider when sampling strains for breeding is the tendency to produce anxiety. Certain strains of cannabis increase anxiety while others decrease it. This is also true for other emotions, which some strains may suppress while others may augment their intensity. Generally stimulating and head varieties are the ones that can produce unwanted anxiety, but this is not always the case. Quickly cured buds or an over-early harvest are contributing factors to anxiety-increasing pot, but this trait is also genetic in nature.

Tastes and tasters

The physical palates of cannabis add another dimension to the equation. Taste is an important factor toward determining the desirability of most cannabis. The range of flavours expressed by the genus cannabis is extraordinary. No other plant on the planet can equal the cacophony of smells and tastes available from cannabis. This fact alone should interest researchers from several fields.

The range of possible smells and tastes a human can experience is large and complex. To date, no-one has created a fully usable olfaction chart, but Ann Noble developed a nifty "aroma wheel" for the wine industry, which inspired me to develop a cannabis olfaction chart. Like Ann's wheel, more basic aroma categories like "fruity", "floral", "spicy" and "pungent" go in the centre, and branch out into more specific aromas. So beneath "fruity" goes "berry" and "citrus", and beneath "citrus" is "lemon", "lime" and "orange".

The main cannabis aromas are: woody, spicy, fruity, earthen, pungent, chemical and vegetative – a wide range indeed. More specific aromas include pine and cedar under "woody", musty and dusty for "earthen", blueberry and mango under "fruity", and many others. Most aromas are possible through some combination of strains. Many of these strains were best expressed and acclimated when they were grown outdoors in their region-of-origin, or homeland.

Note that aroma and flavour vary between various stages of the plant. The aroma of a live bud on the plant, a dried and cured bud, and the smoke on the inhale and exhale, may all be different from each other. My number one goal when breeding cannabis is the quality of the perfectly matured, trimmed and cured bud and the experience it provides.

I strongly recommend the use of "tasters" to help analyze the qualities of a given smoke. I prefer highly educated, seasoned and critical elders as they tend to be the most helpful in their analysis and feedback. If there is the slightest drawback to the product, such as arrhythmia, tachycardia, paranoia, or what have you, the experienced elder taster will be the first to notice it. By the same token, if a product is exceptionally fine, the experienced elder taster will also likely be among the first to fully appreciate this. Besides, the elders always appreciate good medicine.

The best way to educate and train the palate is through experience. Unfortunately, there has been a great depletion of variance among the product available to the public. Most grow-ops focus on quantity over quality, and as a result a general blandness has developed. In future articles I will describe some of the great region-of-origin varieties that were available twenty years ago, describing their aroma, flavour, effects, and growth patterns.
 
Sprouting and planting by DJ Short

How to turn your seeds into healthy young plants

Sprouting the seeds


My preferred method of seed sprouting is the wet paper towel method. Take six sheets of white (non-printed) paper towel and fold them to a roughly five by six inch square (about 24 layers thick). Soak this square pad in pure water and place the seeds in the center fold, with twelve layers both above and below. Keep the pad wet and the seeds will usually sprout in one to ten days. (On some occasions I've had seeds take up to two weeks to sprout, so be patient!)

I have found the ideal temperature for sprouting most seeds to be around average room temperature (70-78°F or 21-25°C) . Though higher temperatures may hasten the sprouting time, the heat will also increase mold, fungus and bacteria levels. So keep a watchful eye open in a warmer situation.

One more bit of advice concerns certain seeds which do not want to release from their shell. The seeds will sprout, the sprout will grow root, and it transplants fine. However the seed shell does not come off of the sprout on its own. The shell seems to harden on the head of the sprout, eventually causing its death if not properly dealt with.

Shelled sprouts

I've found that these rare anomalies need help in shedding their shell or sheath in order to survive. It takes a very gentle yet firm hand to remove the shell without damaging or killing the plant. Under the shell is a thin sheath that may also need coaxing to get off. Again, practice is the best guide for this skill.

I would also like to point out that though this phenomenon is rare,the plants that develop from these stubborn sprouts are usually very desirable. So it is worth the effort, especially if breeding is intended with the sprouts.

Roots and planting pots

At first, the seeds crack open along their seam and send out a white root. I like to wait for the root to grow an inch or two before transplanting the sprouts to soil (while keeping the paper towel pad continuously moist with water until this time). When I do set the sprouts to soil, I like to bury them right up to the head of the plant so the head is right at the soil level. It is important to gently water and feed the sprouts from this point on so as not to disturb the new roots too much. I have found the common turkey-baster to be of great value for this purpose.

The method of planting into soil that I use is very basic and simple to understand. I like to use small, two to four inch pots. A great substitute for planting pots are the sixteen to twenty-four ounce disposable plastic drink cups. These cups can be bought cheaply in bulk amounts at any discount or grocery store. They will each need five or more drainage holes to be added to their bottom, this can easily be done with an electric drill and a quarter to a three-eights inch drill bit. Stacking ten to twenty cups at a time will hasten this process.

The cup or pot is filled with the soil mix, usually a high nitrogen variety for sprouts, and the soil is gently yet thoroughly tapped and shaken down to fill all vacant spaces equally. The soil level should end up to be two-thirds to three quarter of the cup or pot capacity. In other words, there should be an adequate space between the top of the soil and the top of the cup or pot. This is to allow for more soil to be added later as the main stem grows. Once the soil is sufficiently tapped down to at least two-thirds full, it is time to moisten it.

Grow flats and turkey basters


I'll put anywhere from one to two dozen cups or pots per standard grow flat (or tray). Next, I'll fill the appropriate sized bucket or container with the water/nutrient mix. The common turkey-baster is once again the best tool available to evenly soak all of the cups or pots. Larger operations may require some kind of pump and tubing device to aid in the watering.

If the grow flat and all of the pots are relatively clean, then any excess solution may be re-used until all of the soil is at its fullest saturation point. Just prior to this saturation point, I like to use a standard chopstick to poke a hole, as deep as the sprout roots are long, into the middle of the soil. Into each hole more nutrient solution is added to fully soak the medium and prepare it for the sprout. Once the entire flat is ready, it's time to begin the planting process.

Take one sprout at a time from the paper towel, handling it as gently as possible by the stem just below the sprout head, and transfer it to the moist, pre-made hole in the soil. Carefully guide the root tip all the way down the hole, using the chopstick if necessary. Be certain that the root tip is pointing down and not curved up in what is called a J root. J root may be fatal to the sprout.

Once the sprout is situated in its hole, the root is running down the hole and the sprout head is above and as near to the soil level as possible, the soil may be gently packed around the sprout stem to hold it firmly in place.

Water and soil

Next, the sprouts will need to be watered. Despite the fact that the soil is saturated to its maximum capacity, this first watering helps stabilize the root in the soil. This again is gently and carefully done using the turkey baster (or whatever gentle watering device is available) as a watering tool. Once the sprouts are adequately set in the moisture-saturated soil, they will not need watering again until after the soil dries a little.

It is also important not to leave any standing water in the grow flat. The turkey baster is also useful for sucking the excess water from the bottom of the grow flat, to help hasten its dry time. The baster is handy for the first few waterings, when a gentle touch is still beneficial.

In one to two weeks, the healthy sprouts will stretch and grow up over the top of the cup or pot. It is after this time that more soil may be added to help give the sprout more stability and root room. This tip helps deal with the problem of spindly plants by giving them more base support during their early development. This step also promotes and stimulates adequate root growth. New roots will sprout and grow from the soil-covered stem in a week or two.

Hydro sprouting

Hydroponic sprouting is as simple as placing a seed in a rockwool cube or fiber pellet and keeping it moist. The seeds will sprout and root automatically in this porous and nutrient-rich medium. Tying the plants up to stakes will be the only way to deal with stretched or spindly growth in the hydroponic system.

Hydro transplanting is also quite simple. The pellet is placed in a larger rockwool cube or gravel medium and the roots grow quickly into the new material. Hydro systems often need extra supports, such as stakes or poles to hold the top-heavy, weak stemmed plants up.

Transplant time

Transplanting becomes necessary when the roots outgrow the medium. This is evident by checking one or two of the average plants roots. When the white root wad is becoming entwined, growing among itself and beginning to turn brown, it is time to transplant. Special care needs to be taken when transplanting into larger containers to avoid as much trauma as possible.

I like to transplant when the root system is semi-dry, a day or two before a usual watering. The medium in the larger container should be saturated to its maximum density with nutrient-rich water. The semi-dry rootwad is placed firmly into the saturated fresh medium, and the rest of the space in the larger pot is filled with fresh, semi-moist medium. Ideally, the fresh medium will cover the old soil level by a bit, and the loose soil is gently packed into place throughout.

I like to gently shake the soil fully into place and level the soil top by hand. As with the original planting, the fresh transplant is completely watered to its saturation point. New roots will quickly and eagerly find their way into the fresh, new medium, and accompanying growth will develop in the plant.

Happy growing!

The Process

The main room was divided in two with the Blueberry on the left and the Flo on the right. The plants were relatively huge considering how long they’d been in veg. Lush growth dominated as three distinct Blueberry phenotypes and two distinct Flo presented their development, along with a small number of unique anomalies. Of course, all individuals were numbered and labeled and notes were made over the course of several inspections during the flowering cycle.

During this period all of the males were isolated in a separate room and watched closely to enable the best selection from them. From this particular gene-pool, I find it relatively easy to select the best males as they tend to express their traits regardless of environment or light cycle. There were so many to choose from during this process that the difficulty became who to cull out. Most of the males were at least to some degree resinous with glandular stalked trichome, some more than others. This usually makes it easy to test certain profiles such as overall flavors.

Only after the most desirable males are selected (i.e. all the others rejected) are issues of structure and growth pattern considered. Sweet, fruity and floral expressions are most desirable, but attention is paid to other possibilities as well. Top quality candidates of indica, sativa and mutant anomaly are picked by process of elimination. Then those with the best structure; hollow stems, good color and flower density, become the final candidates.

The females also pose the same problem in regard to who is eliminated. Notes are made as to any outstanding qualifications that present themselves during the bud cycle. But it is not until the sixth week in flower, and sometimes not until the eighth week (or longer if the variety is strongly sativa), that the real differences in individuals becomes apparent and the truly amazing qualities shine. And even then, it only amounts to field-notes until well after harvest and the cut-and-dried product is totally cured. It is then that the final selection process begins.

During our selection-crop numerous individuals could have passed the requirements to be a great mother plant. By and large, the overall ratio of desirable plants that qualified for final selection from this crop was approximately 1:10 (employing DJ’s Law). As it turns out the elite ratio of final candidates turned out to be approximately 1:30–the best of the best as it were. By the eighth week in bud approximately two dozen individuals stood out as primary candidates. After these samples were individually labeled and jar cured for about two months, a total of eleven were of supreme quality. Believe it or not, the final elimination process among these eleven was perhaps the most difficult to complete. Part of the sprocess involved selecting one of each of the three Blueberry phenotypes, one of the Flo, one Blue Moonshine and deciding on the possibility of something new.

The Varieties

After the fourth week in bud, generally speaking, certain characteristics become apparent. On the Blueberry side of the room three distinct phenotypes presented themselves, while on the flo side two less distinct phenos appeared. The three Blueberry phenotypes could be referred to as indica, sativa and variegated or mutated. The indica were shorter, denser and had larger calyx and bract leafs making the buds look plump. The sativa were taller, more slender leafed with more elongated buds of dense, smaller calyx. The indica tended to be of a stronger, more musky odor where the sativa were more delicate and floral. The variegated or mutated individuals varied more in their aromatic palate with some seeming more potent than others. On the flo side the difference was less pronounced between phenotypes but two distinct types developed. The primary difference was in bud structure and formation with one type growing with its bract leaves pointing more up and the other with its bract leaves pointing down. Both were more sativa looking with dense buds of small calyx. There was also a difference in potency of aroma between these individuals.

The seed stock “True Blueberry” currently under scrutiny derived from f2’s that were very “BK” or Berry Kush-like. These f2 “BK”’s were crossed with very “TF”, or “True Floral”, sometimes referred to as “Temple Flo”, mates in the f3 and/or f4 generation to brighten the head considerably. Once the right mix was discovered these f4’s (and beyond) crosses were inline bred (filial crossed) to stabilize the proper traits. The “flo” pheno’s are closer to the “TF” (“True Floral”, “Temple Flo”), headier side of the mix, most reminiscent of the Highland Oaxaca Gold.

“Grape Krush” (or “Blue Krush”)–a productive, deep-colored hybrid of very high quality. This plants exhibits partial to full leaf-deformities of the “krinkle” type, but with good structure and heavy bud production of large calyxes. The buds express a strong sharp/fruity odor with a distinct sweet/grape flavor brought out in the cure. A strong, long-lasting head/body mix is evident in the finished product with an exciting, but not “racy”, head and a mild narcotic body. Very euphoric and desirable effects that most seasoned connoisseurs prefer. 50-60 day flowering time.

“Flodica” – a mostly indica phenotype from the flo line. A rare, near-total recessive indica found by chance in the “TF” line (“TF”= “Temple Flo” or “True Floral”). Generally, the flo line sports very sativa like structures of taller plants with slender leaves and spear-shaped buds. The “Flodica”, however, is a near-pure indica phenotype of
short, stout, yet productive, structure with very large, dense, dark indica buds. Very resinous with heavy gland production of an earthen palate to the buds that produce a very strong, narcotic-type experience. 50-55 day flowering time. Unfortunately, the “Flodica” (and the “True Blue Moonshine”) were nearly sterile--i.e. no (or very few) seeds developed, and were therefore culled.

“True Blueberry”–the ultimate hybrid of Blueberry expression. Selected for its superior quality from a large pool, this hybrid contains the best from both worlds (indica and sativa). Medium height with long, fruity and productive buds of medium sized calyxes. Beautiful lavender hues become apparent soon into the flowering cycle. The finished product is of the highest quality with sweet, elongated Blueberry buds destined to please the most finicky palate. High resin production as expected from the “Blue” family. 50-60 days flowering time.

“True Blue Moonshine”–a true “hash-plant”. Selected for its outstanding production of large, clear gland heads, this mostly-indica hybrid really packs a musky/fruity punch. Medium height producing parge, dense buds glistening with trichomes. More musky than fruity with a burgundy/earthen flavor at cure. Top-notch Moonshine. 50-60 days flowering time.

“F-13"–a Holy Grail plant of four-star excellence. Previously unreleased, a very desirable product and potential breeder. A more-sativa hybrid of medium height with long, spear-shaped, dense and resinous buds and an earlier finish time than most sativa. The superfluous quality of the finished product is remarkable: a clear, clean, crisp head of the kindest order with a sweet/floral flavor. This girl really rings the bell every time! Not for the couch-lock crowd, this heady sativa is for those who truly enjoy its stimulating yet comfortable appeal. A real day (or night) brightener. My personal favorite from this batch. 50-65 days flowering time.
 
Breeding tips
by DJ Short (25 Nov, 2002) How to bring out the Sativa and breed the ultimate buds.

To understand the principles behind the breeding of cannabis you first need to be familiar with some basic terms related to genetics. "Genotype" is the genetic and chromosomal make-up of any given individual – it is the genetic code. "Phenotype" is the expression of body type, structure, and appearance of individuals; it results from the interaction between genotype and environment.

Specific environmental conditions are often required for certain phenotypic expressions from a given genotype. If the available nutrients, hours of sunlight, or other conditions are not available then the development of the plant or animal will be altered. These conditions are referred to as "environmental triggers."

Two individuals with the same genotype can have greatly different phenotypes if grown in different environments.

Indoor vs outdoor

In terms of growing and breeding cannabis, there is a distinct difference between indoor and outdoor grow environments. No matter where on the planet one is, the indoor environment is usually far more limited when compared to the spectrum of conditions existing outdoors.

When compared to the wide variety of conditions available outdoors, the indoor environment may be seen as relatively bland and generic. The greenhouse environment, especially when fortified with electric light, is perhaps the closest thing available to a happy marriage

Three subspecies

It is useful to agree, at least in theory, that there are three separate subspecies of the genus Cannabis – Sativa, Indica and Ruderalis.

Cannabis Sativa is the equatorial variety found primarily around 30 degrees latitude North or South. Sativa generally grow tall, from seven to thirty feet, have many long branches, narrower leaflets, and mature slowly.

Cannabis Indica varieties generally inhabit the areas between 30-50 degrees North or South latitude. Indica are generally much shorter than Sativa, only about three to five feet tall. They have fewer and shorter branches than Sativa, the longer of which are lower on the plant, with much wider leaflets. They also mature earlier and more rapidly than Sativa.

Cannabis Ruderalis grow naturally primarily past 50 degrees north latitude (the Siberian steppes). Ruderalis are the shortest, least bushy, and fastest maturing of the three.

The end of the sweet spots

Prior to the late 1970's, virtually all commercially available cannabis products came from the great outdoors. Many of these varieties had been grown in their particular region since antiquity – not since the advent of sailing had a greater diversification and distribution of the herb occurred.

Most cannabis available was also very well acclimated to its particular region of origin. Certain places tended to produce very unique and desirable types of herb that were renowned to each region. I like to refer to these high-quality cannabis producing areas as "sweet spots." The products coming out of these sweet spots during this era were among the finest herbs ever available.

A series of phenomena occurred in the late 1970's and early 80's that has since revolutionized the cannabis industry. This series included the triad of sinsemilla, High Intensity Discharge (HID) lighting, and the introduction of Indica genetics, coupled with draconian herb laws that drove the industry far underground. Never before in human history was so much genetic diversity of cannabis grown in such generic, indoor conditions. The results of this phenomenon have wreaked havoc on the cannabis gene pool.

The road to blandness

As Indica, sinsemilla and HID lighting became predominant, it became apparent that Sativa varieties were very difficult to coax commercial amounts of sinsemilla herb from indoors. The fast maturing, dense bud structure of the easy-to-grow Indica soon dominated the indoor grow scene.

Another factor contributing to the desirability of the indoor Indica was its truebreeding "dioecious" nature, meaning that individual plants tend to be male or female only, but not both. In contrast, many Sativa strains show hermaphroditic tendencies indoors, with male and female flowers on the same plant. (It is my opinion that wild Sativa strains of cannabis are primarily truebreeding hermaphroditic varieties.)

As outdoor production diminished due to intolerant laws and the drug war, indoor production of Indica phenotypes became the staple of the commercial indoor grower. The road to generic blandness had begun.

Although some Sativa/Indica crosses matched some of the Sativa flavor and head high with the Indica bud structure, this desirability would only last for a few generations of breeding. Unless a person is breeding for a very specific trait, crosses seven generations and beyond the original P1 Indica/Sativa cross lose much of their original charm and desirability. Cloning, however, helps to extend a given plant's potential.

Ruderalis: myth and misnomer

As indoor growers attempted to improve their genetic lines via breeding, another interesting phenomenon occurred: Ruderalis. Although there is a wild variety identified as Ruderalis in Russia ("Ruderalis" is supposedly Russian for "by the side of the road") that grows very short and matures very fast, I seriously doubt the rumor that someone actually went to Russia to collect seeds of this variety sometime in the past. Or, if someone actually did go all the way to Russia to find, collect and smuggle "rudy" seeds, I do feel sorry for their waste of time. They could have gotten the same worthless thing from Minnesota, Saskatchewan or Manitoba with much less hassle.

The North American Ruderalis probably originated as follows: After the Indica varieties arrived in the US and became incorporated into the gene pool, many breeders began to cross the earliest maturing individuals with each other in hopes of shortening the maturation cycle.

It would only take a few generations for the ugly Rudy phenotypes to begin expressing themselves. By ugly, I am referring to a strong lack of potency and/or desirability. I know, I was once guilty of the practice myself. It did not take me long to realize that this was a huge mistake in regard to the quality and potency of the future generations' finished product, and all subsequent breeding along this line was ceased.

Many of these manipulated rudies were released on the open market between 1981 and 1986. It was shortly after this period that the grow journals of the era (Sinsemilla Tips and High Times) ran articles about the possibility of a new wonder variety for indoor grows: fast blooming Ruderalis. Rumor had spread to myth and misnomer. Therefore, it may be more appropriate to say that the Ruderalis phenotype was coaxed from Indica genetics, via the indoor breeding environment.

The same applies to many of the Indica dominant varieties available today. Breeders selecting for early, fast flowering or fast growth often miss out on some of the finer and more subtle characteristics available from crossing certain genotypes. My advice to breeders is to wait until the finished product is suitably tested before coming to any conclusions regarding desirable candidates for future breeding consideration.
 
Phenotypic expression

The malleability of phenotypic expression among the Sativa/Indica crosses must also be noted. The variability of phenotypic expression among the f2 generation of a truly polar (pure Sativa/pure Indica) P1 cross is quite phenomenal. The second generation f2 crosses will exhibit the full spectrum of possibilities between the original parents – extreme Indica, extreme Sativa, and everything in between.

However, regardless of any particular phenotype selected from among this given f2 cross, future generations may drift radically. Depending on the presence (or lack) of a number of environmental triggers, an f2 Indica phenotype may be coaxed more toward Sativa traits, or an f2 Sativa phenotype may be coaxed more toward Indica expression. The key is environmental conditions.

This is what distinguishes the truebreeding, ancient acclimated, region of origin varieties – especially the tropical and equatorial Sativa – from the crosses that have happened since. The ancient specimens have a much narrower genotype range, and therefore a more specific phenotype than their contemporary crosses despite environmental conditions. It is up to future adventurers to provide the best possible environmental considerations, along with the best possible genetic considerations, in order to resurrect the legendary happy flowers of yore.

Inducing Sativa

After many years of first-hand experience breeding herb indoors as well as outdoors, I am of the opinion that the two most influential factors involving phenotypic variation and expression among current indoor herb breeding projects are the photoperiod (hours of light per day) and the angle of light in relationship to the growing plant.

Specifically, I find the single most powerful influence to the Indica dominant phenotype is the traditional 18/6 veggie cycle and 12/12 flowering cycle. The 18/6 veggie and 12/12 flower cycle is an attempt, however poor, to mimic the Indica-producing photoperiod. It is my belief that this light cycle strongly influences for Indica phenotypic expression.

Sativa phenotype characteristics will manifest under a more equatorial photoperiod, closer to a 13/11 veggie cycle and an 11/13 flower cycle. This is the light timing range to use to elicit more Sativa dominant expression from your plants.

As for the exact photoperiod formula that I incorporate into my growing/breeding regime, this will presently remain a trade secret. My advice is to experiment with different photoperiods, keep good notes and pay attention. Avoid the 18/6 and 12/12 photoperiods, while tweaking the times a bit differently with each breeding cycle until more desirable results in the finished product and their offspring are noted. Here's a hint: work in half-hour increments or a little less, and good luck!

Angle of Light

Angle of light simply refers to the physical angle of light source the plant is dependent upon for growth. Perhaps the greatest difference between indoor and outdoor environments has to do with the angle of light received by the plant. This is also one of the greatest seasonal differences between the Sativa and Indica producing regions.

Outdoors, the main light source is the Sun, with minor influence coming from nearby reflective surfaces. As a plant grows taller and broader outdoors, that angle of light from the sun changes very little in relationship to the growing plant.

Seasonal changes in angle of light increase the further away from the equator one gets. At the equator there is the least amount of seasonal change in angle of light, only about 20°, whereas at the 45th parallel that change is as great as 45°. At the 45th latitude, the Summer Sun is high in the sky while during early Spring and late Fall the sunlight comes from much lower in the sky. The farther one goes from the equator, the greater the difference in seasonal changes regarding angle of light.

Indoors, the lights typically range from a few inches to several feet from the plant. As the plant grows taller, its physical relationship to the bulb's angle of light changes considerably. Most indoor grow rooms have relatively low ceilings, therefore, raising the bulbs may maintain a similar angle of light early on, but eventually the angle changes. The same differences may be noted among plants directly below the bulb and the plants off to the side of the room farther away from the bulb.

Circular light shuttles tend to emulate the arctic summer and create a confusing signal completely unknown to the equatorial Sativa. Straight-track overhead light shuttles are more conducive to inducing the Sativa phenotype.

Aromatics and flavors

Many indoor growers try to get their budding plants as close to the light source as possible. Though this may increase bulk production of both bud and trichome, I find that this practice tends to destroy many of the finer aromatic qualities of the herb.

Buds too close to the light tend to express nothing beyond the lower lemon/lime aromas of the fruity spectrum. Sometimes the aroma is no better than a strong chemical/astringent odor and flavor, especially those under High Pressure Sodium light systems. The finer berry flavors tend to favor more distance from the bulb, and will manifest more strongly under High Ultraviolet Metal Halide light systems, especially during the latter stages of flowering.

Something akin to a gymnasium building with high ceilings and super 5000W lights hung far from the growing plants, set at a Sativa-tweaked photoperiod, would be the ultimate indoor grow-op to coax Sativa phenotypes.

Sweet spot fantasy

Nothing will ever rival the great outdoor sweet spots for quality cannabis production. Hopefully, someday, somewhere, someone will be daring and lucky enough to get away with re-establishing some of the great genetic lines in their specific region of origin sweet spots.

Equatorial Sativa varieties are of interest for quality herb production (Thailand, Oaxaca, Colombia, Central Africa, etc.) as the Indica zones are more renowned for hashish production. Parts of Nepal tend to produce both excellent hashish and fine Sativa buds, with some plants reportedly living longer than two years!

I hope that I am able to live long enough to once again experience the joy associated with the fine herbal products from the great regional sweet spots of near ancient lore. It has been a long time and I am looking forward to the day
 
General Irregularities/Anomalies of Cannabis Relating to Transgressive Segregation

Some of the Blue Family lines of cannabis (True Blueberry, Grape Krush, etc.) are known to occasionally sport various anomalies and irregularities. The main anomaly reported from these lines is that of the "krinkle" leaf type. Also referred to as a form of variegation this irregularity usually involves a twisting or convolution along half of the leaf divided along the central leaf vein. This anomaly usually affects anywhere from 5% to 20% of a given sample depending on the strain (TB = 5% to 10%, GK = 10% to 20%). In and of itself, this trait does not affect yield or the overall health of the plant. It is merely a simple deformity unique to this line of cannabis.

It is important to know the differences between simple deformities and more complex mutations. Simple deformities and anomalies are semi-common phenomenon whereas genetic mutation is by far more rare and profound. Most of the irregular expressions witnessed in some of the Blue Family lines are mere deformities. Very few are true gross mutations and those are usually sterile or non-viable (usually < %1).

I used to think that the deformities witnessed in certain lines of cannabis were strictly the result of a mutagenic regimen such as colchicine. Variegation in particular is a typical symptom of such a process. If such a process were used on the varieties of cannabis I have worked with, I assume that it was in the Thai lines as that is where most of these traits seem to originate. There is, however, another aspect to consider regarding these anomalies called transgressive segregation.

Transgressive segregation refers to the situation where the progeny from crosses of distinctly different P1's exhibit characteristics beyond what either parent exhibited. A good botanical example is that of the cabbage family from which broccoli, cauliflower and Brussel sprouts developed from the same meager beach cabbage. This is the level of the diversity witnessed in the f2's and beyond crosses of the plants that I have worked with.

The combination of the two very pure, unique and distinctly different varieties of indica and sativa resulted in the extreme variation in the f-2 and beyond progeny. This is where the anomalies, irregularities, eccentricities and effects of transgressive segregation are witnessed and isolated. It is from this extended diversity that new and exciting lines are discovered and isolated. Simple leaf irregularities are no reason to abandon a particular line, and perhaps are an indication of something worthwhile. Suggesting that these anomalies are in some way detrimental to the overall cannabis gene-pool is akin to suggesting that broccoli, cauliflower and Brussel sprouts are in some way detrimental to the cabbage family.

[Side Note: What may have been very detrimental to the overall cannabis gene-pool was the "willy-nilly" introduction of indica and indica-based genes to the equatorial regions of the world–circa 1980's. The tropics are susceptible to aggressive takeover by dominant species and sub-species. This may be what happened to the fine sativa land races of yore–coupled with human selection for production-based indica varieties. Hopefully this phenomenon will be relatively short lived as human selection re-kindles the near-lost memory of the beloved land-race sativa.]

The structural differences witnessed in some of the Blue line individuals including anomalies such as leaf shape, leaf krinkle and color variations, along with basic aesthetic qualities such as range of flavor and palate, issues of duration, tolerance and even shelf-life are more than likely the results of transgenic segregation.
None of these minor abnormalities are in any way detrimental to the overall gene-pool. There do occur very rare instances of freakishly deformed and stunted individuals. Every one of these I have ever encountered has been sterile or non-viable. However, some have produced some of the most unique finished product I have ever sampled in terms of flavor, potency and effect. Unfortunately, these extreme abnormalities are not only rare and sterile, most are also nearly impossible to clone.

Please remember, my number one goal when breeding fine herb is that of the finished product. All other factors; structure, color, growth rates and patterns, leaf shape, odor, flavor, height, flowering characteristics, even potency (please see my other comments concerning bland potency versus exciting quality in my book and other articles), etc. are of lesser concern. My secondary concern is the minimization and elimination of hermaphrodites. This is primarily for the indoor community's behalf, as it is my belief that true breeding equatorial (outdoor bred and produced) strains are all monoecious to some degree. It is the quality of the finished product that I aim for with all of my work. Structural considerations are selected for only after a variety passes the "head/body" test.

Please note also that I consider myself more of an artist than a scientist. I respect science for what it is (discipline and controlled focus) and enjoy its utilization, but for me it is still simply another tool with which to create. With that said please allow me to state that much of the science (definitive recipe) involved in supporting my goal (to discover, create and produce truly good herb) remains somewhat of a mystery to me. Due to all of the truly good herb I have had the good fortune to sample, I am confident in identifying what I consider to be truly good herb–with or without the science. I am equally curious, as are many, regarding the scientific observations, disciplines and discoveries that support this goal.

Toward that goal there are a few points I would like to attempt to clarify:

The Purple Thai. As mentioned before, the Purple Thai was a cross between an outstanding Highland Oaxaca and a very freaky Chocolate Thai.

The Chocolate Thai was one of the most difficult plants to grow. It was dark and very asymmetric, rarely sporting any kind of a definite main-stem for any length of time. It was difficult to clone and very hermaphroditic, producing small airy buds at best. The herb from the Chocolate Thai passed the test (the progeny were at least as good as, if not better than, their parent), but had certain problems otherwise (structural and hermaphroditic). It was also similar in potency to the Highland Thai regarding strength, length and type of high.

The Highland Oaxaca was structurally a different strain (tall, with a definite main-stem, symmetric with less hermaphroditism and better formed buds). The two were crossed and the resulting seeds produced the famed Purple Thai that I was able to use for quite awhile. The Purple Thai exhibited the symmetry and desirability of the Oaxaca with the potency and dark coloration of the Chocolate Thai–the best of both worlds, and its hermaphroditism was much more manageable. It also cloned well. The plants from these seeds also passed the test of equal or improved quality progeny in terms of finished product. Personally I preferred the finished product of the Purple Thai to the Chocolate, not just due to its growth patterns but in terms of the overall effect. The original Highland Oaxaca produced the most desirable finished product, in my opinion, and has yet to be replicated to my complete satisfaction.

So technically the Purple Thai was not a true, land-race acclimated P1. However, as far as I was concerned it fit the bill quite well in that it was very consistent in the sativa genes it carried and passed (nearly identical to the Highland Thai). It was also the closest to producing the desirability of the Highland Oaxaca’s finished product.

 
The Highland Thai, could possibly have been from Burma (now Myanmar), as borders between the two countries are questionable and change. Other drainage systems in the region lead to the Eastern Himalaya, meaning that the "Highland Thai" could have originated from a number of places. The entire Himalayan region has perhaps the greatest concentration of geographic "sweet spots" in the world, many worthy of exploration. The Highland Thai grew much like the Chocolate Thai; asymmetric, with more stretch–especially in the bud structures.

The difference in the finished product between the Highland and Purple Thai was that the Highland Thai was more potent while the Purple Thai was more "kind" ("kind" being more comfortable to endure, especially while tripping). Another way to put it is that the Highland Thai could be more "racy" or "scary" while the Purple Thai tended to be more "relaxed" or "happy". Both had no ceiling or noticeable tolerance effect, and both provided a long lasting experience, as well. Both also shared a very similar sweet/fruity flavored phenotype that was unmistakably Juicy Fruit/Tutti Fruity–the ultimate female breeder (Note: this was from the plants grown locally--Oregon, indoor and out).

Regarding a clue to the equatorial "Holy Grail" such as the Highland Oaxaca and Santa Marta Gold (South and Central American varieties) a certain, unmistakable flavor comes to mind: that of incense cedar/frankincense/burgundy/floral with spicy/savory undertones. Coffee, chocolate and fine tobacco were also present, but the sweet incense cedar is what I most recall from the Highland Oaxaca and Colombian Gold varieties. The Thai was more complex with more spicy/savory aspects atop a finely distilled burgundy (probably more from the cure) and sort of a "dying" floral, sickly-sweet aroma that was unmistakeably Thai herb (sometimes from Hawaiian as well).

An important aspect to note here is that, according to the best of my knowledge, most high quality sativa of the era was in some way shape or form of Thai origin (or greater Himalayan, but for simplicity’s sake referred to as "Thai"). This includes the Oaxaca, Colombian, Panamanian, Hawaiian among others of the late 1970's. Most of it supposedly came from Thai seed stock. Having sampled many of the region-of-origin varieties of the time, I must concur. Many of the Central, South American and the great Island herbs of the time were more than likely of Thai origin. Similarly, today’s version of ‘Sweet Skunk’ (a misnomer for sure) when grown to fully finished bloom and with a long-time cure shares a distinct Thai quality as well.

Therefore, it seems Thai was the fundamental building block for most quality commercial sativa of the 1970's. ("Commercial" is a key word in the previous sentence as I am sure that there were/are many different origins of the regional high quality herbs.) Certain aspects of acclimation must have been responsible for the subtle (and not-so-subtle) differences of the various herbs of the time.

My definition of acclimation is: grown in a specific region or circumstance for enough generations (in-line bred) to impart characteristics unique to the region or circumstance–preferably in an herbal "sweet-spot" such as Highland Oaxaca. This is a very important consideration regarding future resurrection of land race varieties.

Side Note: When I was working with these sativa back in the 1970's it was all done either outdoors or under large florescent systems, 8' bulbs set onto 4'X8' sheets of plywood and suspended from 2"X4" frames (obviously before the advent of HID lighting). This was also before the introduction of the Indica (Afghan) genes, which appeared commercially at the same time as HID lighting (circa 1978-‘79).

The indica, or "Afghan" varieties became commercially available at the end of the ‘70's, and were the polar opposite to the Thai’s and other sativa. It is interesting to note that Afghanistan is west and north of the Himalaya while Thailand (and Burma) is east and south. Short, stout, wide-leafed, very symmetric and adapted to a short flowering cycle, the indica is what brought the musky "skunk" odor to the game. I must say that I was not a big fan of the pure indica "skunk" strain. It is the primary culprit responsible for of much of the couch-lock characteristic found in much of today’s herb. Indica usually has a low ceiling and a quick tolerance buildup. In short, it is boring, bland and dull herb, unless one seeks anesthetization (or hashish production).

In the indica’s defense it needs to be noted that it helped birth the indoor cannabis industry. Without the indica’s fast flowering cycle or its dense bud production or its short stature, the indoor grow scene would be very different today. It was somewhat obvious to recognize indica’s virtues and liabilities for what they were. It was work and dedication to breed out the bad and to strive for the desirable. The primary virtue of the indica variety is that of its contributions toward hashish production.

An interesting side-note to the indica breeding scheme was the initial direction of the cross. I found much better success with the sativa/indica cross (the female sativa crossed with the indica pollen) than with the opposite indica/sativa cross (the female indica pollinated with the sativa pollen). Again, this was primarily for quality of finished product from the progeny. I found my "Holy Grails" via the diversity of the sativa/indica cross.

Other anomalies witnessed from the extreme diversity of cannabis include examples of polyploid expression–triple and quadruple types, twins–including various forms of conjoined twins, double leaf and double root phenomenon, along with extreme variation in odor, color and flavor, etc.

So the successes of transgressive segregation are highly dependent upon the selections made in the P1 and f2 generations. These are the most important generations regarding overall selection. The direction of the P1 cross also seemed to play a part in successfully finding high quality herb.

That is all I have time for right now. Feel free to add comments to this thread and I will attempt to answer any questions as time permits. (Please forgive me if I do not respond soon to an inquiry as my life is anything but stable at the moment--hopefully later this year--but in the meantime wish me luck on finding a suitable locale for some serious r & d!) Thank you to all who contribute and partake in this sharing of information--your input is appreciated. So take care, have fun and please keep the discussion flowing.

peace/out

Harvest Your Herb
by DJ Short

There are several important points to consider when choosing the optimum time to harvest your cannabis crop. There are different factors to consider between indoor and outdoor plants. There is the difference between Sativas and Indicas in bloom duration and final effect. There is the difference between early and late harvest to encourage head to body high respectively. There is the issue of chemistry because what we are really considering in terms of the "ripeness" relates directly to the chemical nature and state of the plant at harvest. Last, but not least, is the concept of "the window of harvest", where I will begin.

The Window of Harvest

This term indicates the period during which the plant is at its optimum state of ripeness. The window "opens" when the plant is first ripe. Somewhere along the line the plant becomes over-ripe which signifies the "closing" of the window of harvest.

For most Indicas grown indoors, the window of harvest is about two weeks long * give or take a couple of days for various strains. Indoors, if going directly from an 18/6 hour vegetative light cycle to a 12/12 hour bud cycle, most indicas take about eight weeks to fully mature.

As to outdoors I can only speak from experience at the 45th parallel and the bloom times there. At the 45th parallel I've found most Indicas to be at peak harvest starting at the beginning of October, sometimes very late September, and running until the end of October, sometimes running into November during mild years or in a greenhouse. My favorite time to harvest a nice Blueberry Indica outdoors is in the second to third week of October.

For Sativa grown either indoors or outdoors, the window may be open much longer. Some Sativas take up to thirteen weeks to mature indoors. Outdoors many will go well into November and even December, if conditions are right (again, this is near or at the 45th parallel).

Head High or Body Stone?

An important consideration has to do with one's preference for a "head" high or more of a "body" high. A good head high can positively influence one's mental state much like a psychedelic; whereas a good body high is more similar to a narcotic effect. Generally, head highs tend to be more up and body highs tend to be more down. Suffice it to say that a good healthy mix of the two is a fine goal to achieve.

Sativas and early window harvests tend to be more of a head high, whereas Indicas and late window harvests tend to be more of a body high. Given this rule of thumb you can pretty much come up with what you want. That is, if you prefer a very psychedelic head high, then an early harvested Sativa might do best. If a very narcotic body high is desired, then a late harvest indicas would probably do best. For that best-of-both worlds high, experimentation with late harvested sativas and early-to-mid harvested indicas usually proves interesting.

Magnify your Buds

When we speak of various highs experienced by different products, we are noting variations in plant chemistry. The chemicals we enjoy are produced within the glandular stalked trichomes, along the surfaces of the bud flowers (calyxes), bracts, leaves and stems, starting in or around the fourth week of the bud cycle. More and more of these trichomes develop as the plant matures.

I highly recommend that the serious cannabis student acquire a 30X power, illuminated magnifier. These can be found at most local electronics stores, often for under fifteen dollars. With the aid of the magnifier one can learn more about the detail of trichome development and ripeness.

As far as trichomes are concerned, the tall ones with swollen, clear, bulbous heads are what to shoot for. The denser the concentration, the greater the potency.

The Cycle of Plant Maturity

Starting in the third or fourth week of the flowering light cycle, glandular stalked trichomes will begin to form along the surfaces of leaves, flowers, bracts and stems. At the same time, more and more flowers (also called calyxes) develop into densely-packed floral clusters.

The pistils of the young flowers are bright white and turn reddish brown with age. The pistils and flowers develop from the bottom of the bud to the top. The older, lower pistils are the first to turn reddish brown. For most basic indicas this usually happens by the sixth week in the flowering cycle. It is about this time that the calyxes begin to swell.

Calyx swelling is a major indicator of peak maturity. The lowest, oldest calyxes swell first and the swelling works its way up to the highest, youngest flowers on each bud. At peak maturity about 90% of the calyxes will almost look seeded, they are so fat. Three quarters to 90% of the pistils will have turned reddish brown as well. For a basic Indica this takes well into the seventh week of the flowering cycle.

By the end of the eighth week most of the calyxes will have swollen and a surge of trichome development has coated most of the buds. It is now that the development of a very discerning palate comes into play to determine the finest harvest time. Remember - patience is a virtue and often a discipline.

The ripening signs for most Sativas are highly similar, except extended over a longer period of time. Occasionally, some Sativas have windows of peak harvest that actually open and close. That is, for a week or so the plant may exhibit signs of peak ripeness. However, a week later the plant may have a growth spurt, which lowers the trichome-to-fibre ratio and overall potency for a little while. Usually a fibrous growth spurt is accompanied by a corresponding trichome increase. Again, time and experience are the key elements in this regard.

Changes in Chemistry

As the plant matures through its window of harvest its chemistry changes. As the window closes, the more desirable compounds begin breaking down into less desirable ones. Primarily it is THC breaking down in CBNs and CBDs.

Which particular combination of chemicals is the most desirable is purely a matter of taste and choice, developed over time and with experience. Set and setting also play an important role in determining which type of product is best appreciated.

Pleasant head highs are often desirable for social occasions, whereas a narcotic late-window Indica may work better as an evening medicinal herb. The main point is that these differences are chemical in nature and more research is needed to more fully understand this phenomenon.

Article Taken From: Cannabis Culture (Issue #13)
Written By: DJ Short

Proper ventilation and air circulation are essential to growing healthy, happy plants.

An important aspect to consider when growing plants indoors is proper ventilation, air circulation and temperature control. This practice becomes especially necessary when working with lights over 400 watts, in very small spaces, any time the temperature exceeds 32°C (90°F), or if the humidity gets too high.

The Perfect Temperature

Though sense of feel is adequate to gauge the "perfect climate" for a given plant, there is no real substitute for a thermometer and humidity gauge.

Thermometers are cheap and accurate enough for our purposes. I usually employ several thermometers in different areas in and around the grow room. Somewhere between 32-35°C (90-95°F) is the absolute highest room temperature your plants would care to tolerate. The perfect temperature would be somewhere between 24-29°C (75-85°F). Peaks of 38°C (100°F) are allowable for most strains, but not for any longer than a half hour or so. And only above the root level.

Roots and Aeration

The main area of concern involving temperature are the roots of the plants. Ideally, the roots should be kept at as constant a temperature below 21°C and above 10°C (70-50°F) as possible. The fact that warm air rises and cool air sinks works to our advantage in this case. Also, the plants end up under the larger lights by the flowering cycle, and so they're usually large enough to help shade and cool their root areas.

Still, some rooms build up sufficient heat to require a separate circulating fan, or fans, focused specifically on the root systems. A soil thermometer may be a wise investment.

Proper aeration of organic based soils is crucial in high temp/humidity areas. Perlite and vermiculite, are the tips here – add more to the soil if need be. In hydroponic systems make sure that the nutrient water temp is below 21°C (70°F). If necessary, store the reservoir outside of or below the grow room.

Squirrel Cage and House Fans

There are many different types of fans and air movers available on the market. Most fans can be purchased at the average home improvement store. Proper research and smart shopping will net the best purchases. Careful planning will help avoid costly mistakes. Using the "hot air rises, cool air drops" rule, one can figure out the right solution.

The two most common types of fan are the squirrel-cage and what I call the "common house fan" (box or oscillating fans). Both come in a seeming endless variety of shapes and sizes. Generally speaking, squirrel-cage fans move air either in and/or out of the room, while common house fans move the air up, down and around the room. There are also neat little "muffin" fans that can be used for many things such as light-hood venting and passive ventilation systems.

A passive ventilation system is one that moves air either in out of room (not both). The room is not sealed and so air exchange is allowed free movement from inside and outside the room.

Squirrel Cages

The squirrel-cage fan is the most popular fan for moving large volumes of air into or out of a room or rooms. A common placement for this fan is inside of the room, up high, blowing out. This will help move the hot air out. This method is what is used to stimulate the passive intake of cool air with vent holes cut in the floor or lower walls to access the cooler areas outside of the room.

Other hardware such as dryer-vent tubing or muffin fans may be used to best access the cool, dry air outside of the grow room. It is a simple step further in this type of system to add an oscillating fan or two on the floor, pointing at any angle up, to help circulate the cooler air up and around the plants. This is the simplest of vent systems and works quite well. Choosing the correct squirrel-cage fan is part of the trick to success.

Measuring Air Movement

Squrrel cage fans are rated by their volume of air movement in cubic feet per minute or CFM. A fan with a rating of 100 CFM is able to move 100 cubic feet of air per minute. A room that is eight by ten feet and eight feet tall holds 8 X 10 X 8, or 640 cubic feet of air. Therefore, it would take an optimally running 100 CFM fan 6.4 minutes to fully circulate the air in that room.

Generally speaking, most fans move a little less than their rated CFM due to intake resistance or a dirty fan cage. Bigger fans usually will work more efficiently. Potentiometers, or a "volume control", could be installed in the power line of the larger fans to adjust the fan speed. This would give further aid in the specific control of air volume and ventilation.

Automation

The ideal ventilation system utilizes automation in the form of thermostats and regulators. A thermostat, as with the common household thermostat, would cause the fans to turn on at a certain temp, and turn off at another. That is, a sensor would turn on the fans on at around 30°C (86°F), and turn them off if the temperature dropped below 21°C (70°F). A well-stocked, high-tech grow shop will have several types of thermostats available in a variety of systems.

Box and Oscillating

Common summer house fans also come in a wide array of types and sizes. The most common being the box and the oscillating. Box fans are self explanatory. They can be used in a variety of ways, depending on the innovation and imagination of the user. Experimentation will yield the most efficient uses for these devices.

Oscillating fans are perhaps the most efficient devices for circulating air in a room. The gentle back and forth sway of the fan is very beneficial for the developing plants. These fans tend to keep anaerobic molds down by constantly freshening any potentially stagnant air. There are wall-mounted styles available as well. Home improvement centres carry a large array of various types and styles of air-moving fans, some relatively inexpensive.

A warning needs to be expressed concerning the cheaper, discount-store, oscillating fans (or any cheap fan for that matter) that have a tendency to burn out after a period of time. Some of these products are potentially dangerous if left plugged in and turned on after they burn out.

Therefore, it is a wise idea to check one's fans (and all electric devices and equipment for that matter) on a regular basis as often as possible.

Noise Concerns

Another fan consideration is noise. Some fans, especially the squirrel cage, may be a bit too noisy for a given situation. There are higher quality fans available that do run more quietly – expect to pay more, of course. It also helps to mount the fan directly to a main stud or support, by at least two of its support holes, and preferably more.

Rubber dampers and gaskets can be easily made and used on the support holes or around the overall mounting surface. Keep the fan's bearings sufficiently lubricated as well.

High Humidity

Humidity is another factor that influences the overall quality and quantity of a crop. Generally speaking, high humidity (over 80 or 90%) is bad. It inhibits plant transpiration and ultimately stunts growth. Mold and fungus love high humidity as well. Note that warmer air holds more moisture than cooler air.

There are a few simple practices to help reduce humidity. First and foremost, keep the room as dry as possible. When watering, use just as much as the plants need. Pump, siphon or mop up any remaining water and remove it from the room.

Keeping the room clean also helps. Moisture likes to hide and store itself in material such as dead leaves, spilled dirt or any garbage. Therefore, keeping the room clean and free of debris will help keep moisture and organisms such as mold, fungus and bacteria down.

Temperature and moisture levels directly affect the plant's ability to metabolize nutrients and supplements such as fertilizer and carbon dioxide.

If these practices fail to lower humidity enough, the only solution may be a de-humidifier. However, de-humidifiers are expensive, consume a large amount of electricity and produce heat. These factors will need to be considered in choosing whether or not to employ one.

Ventilation and Circulation are Essential

Proper ventilation and air circulation are essential to maintaining a healthy indoor grow environment. The basic rule of thumb is to move the warm, moist air out and to move the cool, dry air in and around the plants and their roots. Many various types of fans and devices are available to achieve this goal.

Careful planning, basic research and smart shopping will acquire all that one needs to keep it cool and dry, and experimentation will fine tune the system to provide the most perfect indoor environment possible.
 
Root your toot by DJ Short

The right soil and nutrients are key components to having phat, happy buds.

The best indoor buds are soil grown. Actual organic earth allows buds to produce flavours, tastes and effects which cannot yet be reproduced in hydroponic systems. Unlike hydro systems, soil is not meant to be a sterile medium. Quite the contrary, the best soils are very much alive and thriving.

Superior soil

It is possible to grow plants in specially prepared soil that will require no fertilizers in the water later on. There are a number of such commercial and specialty brands of potting soil on the market today. Most are not completely organic and may contain unwanted chemicals. There are some smaller companies up and down the West Coast, among other areas, that do make clean products. It is up to the consumer to shop around in their area and get familiarized with the brands available in the local market.

Even the good local products tend to skimp on some of their ingredients. This is why I like to supplement any commercial soil I use. The two main additives I use are worm castings and a bat/seabird guano mix. For soil used in the vegetative stage I like to add more worm castings than bat/seabird guano. For soil used in the bud cycle it's the opposite - more bat/seabird guano than worm castings. When one gets to know one's local products well and gets the mix down just right, the resulting success becomes evident.

The following is a simple recipe for a soil mix that has proven successful for me in the past. The bulk of the mix – about 70% of the finished product – is made up of equal parts peat or sphagnum moss (I prefer coarse cut sphagnum moss) and perlite. Then worm castings are mixed in to about 15% of the finished product. About 10% of the finished product is made up of some kind of organic compost, either green or brown. Any rich green manure will do, or bat/seabird guano or seaweed for that matter. The final 5% is made up of a mixture of about equal parts trace mineral elements, granulated charcoal, washed sand and volcanic ash. To this mix a specific dry fertilizer may be added, depending on if the soil will hold a plant in vegetative or flower cycle.

The mixture then needs to be moistened. The perfectly moistened mix will hold together as clumps when squeezed but will not release any more than a drop or two of water. As with many other aspects of life, practice makes perfect.

Organic manic

As for nutrients and supplements, there are many on the market. My preference is for the most natural and organic substance available. Many fertilizers are made from industrial chemical sources and do not, in my opinion, produce the highest quality. The more natural elements are by far preferred. These come from the more obvious natural sources such as worms, fish, bats, birds, plants and seaweed. Green manure, or rich–composted plant matter, is another excellent source of food for plants. As for where to find a reliable organic garden supply store, well, if the store clerk says anything to the affect of: "chemical or compost, it don't make no difference," then you are not in a reliable organic garden supply store. It is a large consumer market to be explored.

Some people choose to feed their plants by spraying a nutrient solution onto the plant and having it absorbed through the foliage. Though "foliar feeding" does work, I tend to avoid doing it due to the fact that the foliage is inevitably going to be smoked. There is no guarantee as to how much residue remains upon the foliage, or what exactly that residue may be, when it is finally consumed. Therefore, it is important, especially during the flowering stage, not to use the foliar feeding method on any part of the plant that is destined to be consumed. Foliar feeding during the vegetative stage on the larger shade leaves that will be discarded is a relatively safe practice.

Nutrient knowledge

The primary knowledge concerning fertilizer and nutrient (other than its source) are its N, P, and K levels. N stands for Nitrogen, P stands for Phosphorous and K stands for Potassium. These are the three main nutrients that plants need to thrive. Most fertilizers have a number consisting of three numbers such as: 30-10-10, or 5-37-15. These numbers represent the ratio of nitrogen, phosphorous and potassium (in that order) in the product. That is 30 parts N (nitrogen)-10 parts P (phosphorous)-10 parts K (potassium) is what is in a 30-10-10 fertilizer. An additive I like to use with every fertilizing is a B-vitamin hormone supplement such as Super Thrive. This product helps the plant better metabolize its nutrient uptake, and most are organic.

High nitrogen, low phosphorous, low potassium fertilizers stimulate foliar and stem growth in the vegetative stage. In contrast, low nitrogen, high phosphorous, high potassium fertilizers promote lush flower, bud and fruit growth in the bud or flower cycle.

I like to end all nitrogen to the plant at least five to six weeks prior to harvest. And I like to end all additives to the plant two to three weeks prior to harvest. A B-vitamin hormone such as Super Thrive may be given up to the last week. But I highly recommend a pure water flush for at least the last two watering times.

Nematodes and tea


Teas made from bat/bird guano and/or worm castings and/or green manure are an excellent source of organic nutrient. These teas are simple to make and easy to use. Prepare a container with enough water for a full watering. Next, add the bat/bird guano, worm castings and/or green manure to the water. Finding the "perfect amount" to add will take some practice. The nutrient is allowed to sit and "steep" in the water releasing the nutrients' water soluble properties.

Another method is to use the full amount of nutrient in a smaller amount of water to create a concentrate. The concentrate is then added to the full amount of water for watering. The tea will color the water similar to the shade of the nutrient (usually brown, but sometimes green as with green manures). The steeping takes anywhere from one day to several days. The teas are considered fresh when made. It is important to use them immediately when they are ready, and to not allow them to stand too long and stagnate. The tea is applied the same way the water is during watering. This is the preferred method of adding organic nutrient during watering.

Another great additive for the organic garden are beneficial nematodes. These microscopic, living organisms are found at the more complete organic garden centers. Beneficial nematodes are cultivated and sold live, usually refrigerated. They must be kept refrigerated until they are ready to be used. They usually come in a sponge, or some other porous medium. It is only necessary to use a small portion each time as they will reproduce profusely if properly introduced into the soil.

A small portion of the nematode colony is simply introduced into the water, (tepid - not too hot, not too cold) with or without the organic fertilizer, and soaked into the soil. Once in the soil, the nematodes do their thing by multiplying and consuming the things detrimental to the plant, such as fungus, spores, insect larvae, mold, and bacteria, while leaving the plant to thrive. Ideally, beneficial nematodes may be added as often as desired, but once every month or two is sufficient.

These are the basics when it comes to growing medium, nutrient and additives. This information was gained via experimentation on advice given to me in the past. Now it is your turn.

Hydro Power


Hydroponic medium is any sterile medium that will hold some water, but allows water and air to pass through. Gravel, perlite, rockwool, volcanic pumice, rock corn and sand are some examples of hydroponic mediums.

Most hydroponic systems provide nutrients via the water that is passed over the rocks several times daily. These systems consist of a reservoir, a pump (or pumps), tubing to carry the fluid to the plants, the pots and medium that hold the roots of the plants, and some way for the water to flow, or be pumped, back into the reservoir. The water soluble nutrient is mixed with the water in the reservoir and delivered to the plants via the pump and tubing several times a day. Most systems also utilize a timer to automate this process. There are also ebb and flow, PVC pipe, wick and various other passive systems, but they are much less common.

Hydroponic systems are famous for producing the largest amount of foliage and fruit. The plant does not have to put as much energy into its roots and therefore has more energy for foliar and bud growth. Also, the roots are regularly aerated and thus have excellent oxygen exposure. However, The incessant regimen tends to produce more of a bland finished product.

The entrepreneurs in the hydroponic industry are striving for the most natural hydro system, and are experimenting with many new nutrient products to achieve this end. I have, however, yet to sample a hydroponic grown product that surpassed a soil grown product in overall quality and flavor.

The same can be said about indoor versus outdoor growth, as well. That is, when grown outdoors in the right environment the finished bud is usually superior to its identical twin grown indoors.

COLUMBIAN

Colombian Gold

Colombian Gold came from the highland Colombian valleys near the equator, as well as on the coast (the Caribbean and the Pacific).

This was specialty pot offered commercially in the mid-70's, for about $60 to $100 per ounce. It was seeded, but most of the seeds were undeveloped, white and useless. A few rare, viable seeds were found that were dark, small-sized and roundish. The buds were leafy and the most beautiful golden blond color. Legend has it that upon maturity the plants were girdled, then left standing to die and cure in the mountain sun and mist.

The color and cure were unique, and the aroma, flavor and high were equally so. The smell was that of sandalwood incense, almost like frankincense. The flavor was that of a peppery cedar. It was some of the most unique tasting herb in the world, and the high was just as exciting. It was truly psychedelic, powerful and long lasting.

First came the great flavor, then the stupefying awe of the shift in consciousness followed by a giddy excitement and bursts of joyous laughter. Smile-lock and red-eye made it painfully obvious who was under the influence of this great psychedelic herb.

The plants from the seeds of the Gold were primarily of Sativa origin. They grew a medium to tall size outdoors at 45°N (Seattle), and were mostly symmetrical. On occasion the symmetry was interrupted by one side outgrowing the other, causing a rounded and bulging tipped bush look. The leaves were long and slender.

When grown in Washington state, the finished product was a sweet, spicy Sativa bud that matured around mid-November. The high was adequate but not as good as the Oaxaca Highland grown at the same latitude. The plants were also slightly hermaphroditic.


Colombian Red

Colombian Red was the near polar opposite of Colombian Gold. This lowland jungle pot (possibly from Brazil) was made up of dark red, almost black, chunky little nuggets of what appeared to be hash, stems, leaf and seed. The aroma was that of cedar and hash.

In the early 1980's, the Red cost only $30 to $60 an ounce due to its appearance, making it one of the best deals going. This pot was a narcotic, knock-you-down-and-out, super munchie, red-eye express. The joints would only burn half way before drowning in their own resin! The smoke was very expansive in the lungs with a powerful pine/hash flavor.

Before subjecting its victim to fits of gorging and deep snoozing, the experience usually included ridiculously long spasms of uncontrollable laughter. The silliest little image could induce hilarity beyond belief. This was the main herb around when the Cheech and Chong movies first came out.

The plants from the Red were among the first grown out by Americans. There were many seeds, medium-sized and dark grey, that sprouted and grew easily into a finished product that was more than adequate. The plants grew low, dark, and bushy, with uneven and somewhat scraggly branches that were easily broken from wind damage. The locally grown varieties rarely budded very much, so it is not certain when they would have finished. It would have been relatively late in November at the earliest.
MEXICAN

Highland Oaxaca

Highland Gold, somewhat similar to the Colombian Gold, lacked bright gold color but sported purple and red calyx tips on its blondish-brownish-green buds. It had larger buds surrounded by long, skinny leaves.

I smoked this variety during brief periods in the early 70's and again in the late 70's, paying anywhere between $40 and $120 per ounce. It was some of my all-time favorite because the aroma and flavor were of a super-spicy cedar incense with a slight fermented berry taste, in a very comfortable yet powerfully psychedelic pot. This herb contributed to many great parties, concerts and events of the era because it produced a very socially-conscious experience and mixed well with other psychedelics.

With a long lasting, creeper high that kept coming on in waves over the hours, this stuff had no ceiling. One phenomenon consistently reported from the Highland Oaxaca experience was that of peripheral visual distortions of primarily cartoon color images. This tended to increase the visual distortions caused by other psychedelics such as mushrooms or LSD.

The Oaxaca Highland Gold was a nearly pure Sativa which grew tall at 45°N, outdoors. It was also one of the most symmetrical Sativas I have encountered. The plants grew long side branches toward the bottom, and the even growth made these productive beauties look like Christmas trees when mature.

The finished product was a very sweet and spicy herb of the highest quality, with a hint of fruity pine aroma. The seeds for this variety were small, dark and round, and the plants exhibited slight signs of hermaphroditism and required surveillance to maintain seedlessness.

Guerrero

This strain from Mexico's coastal mountains came in famed green, seeded spears and cost $60 to $120 per ounce in 1977. It had a spicy, almost wintergreen fragrance compared to the other Mexicans with a very clear head high and a most pleasant smoke. It was not as strong as most, but this herb still had a way of satisfying all its own.

There was a legend about a group of entrepreneurs who imported seed from Lebanon to Guerrero and grew the famed Lebanese Upper Mountain (LUM) from the late 1970's to 1980. The LUM was electric, psychedelic and slightly sedative as well. A unique herb that I wish there would have been more of.

The seeds from the Guerrero were medium to large in size and grey to green in color. The plants from these seeds grew similarly to other Mexican and Colombian strains: a medium to tall, bushy, productive plant. The Guerrero Green, however, is where some of the famed onion and garlic flavored bud of the Pacific Northwest originated.

Michoacan Brown Spears

From the high valleys of Michoacan, this strain was very similar in shape and texture to the Guerrero, but dark brown, and with a more peppery, spicy, woody aroma. $40 to $60 bought a seeded ounce in 1975. Although it was somewhat more bland tasting than the Guerrero , this semi-commercial pot was by far better than the commercial Mexican that was all too available. It had a more distinct, spicy flavor than the regular Mexican, as well as a brighter high that was not as susceptible to tolerance or burnout.

The plants from the Michoacan Spears were nothing great. They were thick and bushy and matured earlier than the Colombians. Some were ready in late October, but most were ready in early November. The seeds were medium grey and plentiful. Like the Guerrero, they produced some unique spicy flavors when grown outdoors in the Pacific Northwest.
