Not to worry! You are good. Cold water doesn't do anything to "pistils" which are the overall female part of the plant (comprising of stigma, style, ovaries). He's referring to signaling the plant to shut down. You did well. Staging trichomes is easy - lots of stuff on the net. It goes...

Really, your best options are to choose fast maturing varieties and, as already stated, trimming to maintain an open airy canopy. Have you considered daylenth insensitive versions of your favorites (meaning autoflowering forms)? Other than that, avoid outdoor cultivation in your area. You...

Nicely Done! If you want a nice reference for Cannabis check out Dr. Ernie Small's book: Cannabis: A Complete Guide. It's on Amazon for $70 Cdn. or $140 for hardcover (25% less in US dollars). He literally wrote the book on Cannabis; he was Canada's primary research scientist (botanist)...

OK - I'll jump in - I'm in Canada, grow tents are kept no higher than 50% RH and the house they are in is set for 50% RH with a real serious dehumidifier. I've never had to nor do I use a humidifier. My 5x5 has the new G8-C3 LED and my 3x3 the old blurple G8-450 vedge/flower + UFO red light...

It'll work - I use a very similar system (sex them in 4x4x5 black pots, transplant directly to autopot XL system)

I've been dealing with CropKing Seeds (Vancouver) for over 3yrs now (over 10 varieties) now - including free seed replacement for a mixed-up order (they let me keep the seed they mistakenly sent). All my dealings have been as expected. I'm Canadian however, and I use Interac (debit) NEVER a...

I also went with the Autopot XL system...just before they came out with their much more space-efficient trays. So I've got six individual large pots with aeration domes, pumped in air at the roots and a 100litre gravity-fed reservoir. I had to build a support stand to elevate the resevoir. The...

your experience could be due to a couple of things - mostly related to your choice of growing medium - my first thought is pH issue - I don't see any chlorophyll in those cotyledons.

update: went with the G8-C3 for my 5x5 - it's awesome - blindingly so!

For a starter (background on plant breeding) I would go with Dr. Walter Fehr's two volume set on Principles of Plant Breeding. Fehr is a breeder/professor from Iowa State. Simmonds is OK. The really old text on Plant Breeding from Allard (UC, Davis) is still one of the best basic books but...

you might want to include the following in your deliberations: G8-C3 light for 5x5 and G8-C2 light for 4x4. High efficiency, rocking PAR #'s, can operate 12" above canopy easily, no burn. I went through the same process as you and ended up with a C3 for my 5x5 - no regrets at all - haven't...

Looks like some Peronospera (powdery mildew) mixed in with some nice frosting - went through the same thing a couple of weeks ago. The acid test is to lightly rub one of the white areas on a leaf - powdery mildew will wipe off easily - like dust. treatment? wipe down leaves then spray whole...

It's five months since this e-mail. I'm shopping for a 5x5 tent light too. I've got it down to the new HLG 650 Diablo and the new G8-C3 - both game changers but quite different. I favour the G8 model myself because it has a vedge and flower setting (different wattage). The HLG has unreal...

Yes - I've used their mid-level LED light (450, vedge&flower) with an extra flower booster (UFO light) for the past 3 years (5 grows) in a 3x3 tent - flawless, high yields, short internodes - very high quality lighting. I use it in my males tent. I bought what was purported to be one of the...

I know what you mean. If the seed source was good and the breeding legit, an F1 could be uniform and stable but in the real Cannabis seed world, it is usually variable. Cannabis is a population based species so so-called hybrids are really population based hybrids - yes, there will definitely...

Almost looks like you are using orchid mix there! - Try ANY soiless mix that is sterile (coco coir, coir/perlite mix, HP mix with micorhizae (no fert version), etc.) and simple mineral water. Trickiest aspect is after 12hr seed imbibing in water (cracked seed coat) - - when you go to paper...

You bought an autoflower so the normal daylength sensitivity genes have been neutralized (by crossing with daylength insensitive Cannabis ruderalis). Bottom line is this plant will likely fully mature in window sill culture (if in Northern clime - you'll need supplemental light during Northern...

with those parents you'll be pushing 30%

All I can tell is that you've got a 6x4 grid of HPS lights - I'll assume 1,000W which puts your room at somewhere between 400 and 600 sq ft. if you've lighted up properly. I think I see an air handler unit (dehumidifier?). You're using HPS - judging by the solid yellow spectrum (doesn't look...

Technically YES but practically - why bother? Fruit maturity and plant senescence (chloropyll bleaching, leaf senescence, etc.) are linked by separate processes in a plant. One follows the other. It is possible to be harvesting fully mature buds/colas off a plant while the plant itself hasn't...
