blackout for 3 days end of flower

Informal fallacy, an argument of ignorance. It has not been proven false or true.

I gave my experience, but what I say I saw could be from the placebo effect because I here about dark periods making such a great difference at least once a week on here and other forums. I've accused many others of the placebo effect, and it could very well happen to me just as easily.

I honestly don't know if its true or not, so I guess nobody will know the truth unless scientific research is done, but I doubt that will happen anytime soon.

Note to viewers of this thread: Take what I/others say with a grain of salt, just like I do with EVERYTHING I read on forums.

This goes for everything, whether you see it on the interwebs or not! I think one way to really cement a concept in your own head is to work with it yourself. One is likely to respect s cliff a lot more after examining raw eggs tossed from the top!

For me it's always about moving forward with my grow, I like to try things, and lots don't work but some do, and if it increases yield and or potency I'll try it once if it makes sense. That's how we make advances we can all share, and keeping an open mind is how we learn. Pot growers are a very talented lot and rig up some amazing things and think up some interesting things like this light's off for extended period of time. Does it work yes, no or maybe? 1 day, 2 days or 3 days who knows that's the question were asking.

I always chop just before lights on and always have so adding 12 to 24 hr is not that big a deal, just hard to prove if it works. I do have to say I have not heard any large grows in BC or the states doing this has anyone heard anything.

Seamaden where are you? You have connections ever heard of it.

and btw, by not citing your sources, you indeed -are- taking credit for others work (or bullshit).

on the contrary, when I see unsupported cutandpaste truth statements like that posted to forums, I'm usually smart enough to be suspicious of the source's credibility.

and I am sure if you saw Obama walk across water you would say he can't swim.

"In the 1970s, Dr Carleton Turner at the University of Mississippi found that there was a variation in the amount of THC in a sample, depending upon the time that the plant was taken. The most potent point was just before dawn after nighttime darkness.

Then, in 2000, Dr Paul Mahlberg of Indiana University showed that THC was produced extracellularly, on the inside of the glandular membrane, which would allow for its daily recycling.

The idea of using a dark period to increase THC before harvest warrants some investigation. An extended dark period right before harvest might very well increase THC content."

-Ed Rosenthal issue of Cannabis Cullture.

The Stichting Institute of medical marijuana (SIMM), the first company to sell marijuana through the pharmicies of Holland, has been investigating the medical possibilities of cannabis, together with TNO laboritories and the University of Leiden.

One of their discoveries has been that to keep the ripe plants in the dark before harvesting could increase their potency.

SIMM's growers separated a crop of mature plants, harvested half of them and kept the other half in absolute darkness for 72 hours before cutting and drying.

Analysis of the resulting dried buds showed that some varieties had seen increases of THC of up to 30 %, while the CBD and CBN remained the same.

In nature there is no form without function. Cannabis plants do not create THC so we can smoke their buds and get high. Trichomes, and the sannabinoids and terpenoids in them, are a defense against various things. THC works as a sunscreen to protect the delicate inner glands in glandular trichome heads. During each period of light some THC is degraded and then during the next period of darkness that amount of lost THC is replaced plus a small amount more is added. That is the reason why adding UV-B lighting to indoor grows increases the level of THC.

To make this as simple as possible let's say there are 'particles' of THC within a glandular trichome head, let's say there are 10 THC particles. During hours of light say 3 of the 10 particles of THC are degraded leaving 7 'particles' of THC. During the next period of darkness those 3 degraded 'particles' of THC will be replaced and an additional 2 will be added, meaning there are now '12 particles' of THC for when then next period of light begins. That process is repeated over and over again during the flowering stage of growth causing a slow but ever increasing number of THC 'particles.'

When plants are given an extended period of darkness the plants do not have the daily loss, the daily degradation, of THC as it protects the delicate inner glands from UV-B light waves. Plus the plants are in their 'night function mode' where more THC 'particles' are being produced than during the day. So over the 72-hours you have no loss of THC due to light degradation and at the same time you have the 'night function' increased rate of production of THC occurring. The two combine for what can, in some strains, be a significant increase in levels of THC, and a lesser increase in other strains. Like so much in growing it appears to be strain dependent on just how great of an increase there will be, but there will be an increase. It might be so little that it could only be detected using gas chromatography coupled with mass spectrometry and it might be great enough to knock your socks off.

All someone can do is try it and see if it is worth doing with the strain or strains they grow.

the other stuff yeah, but shallow and pedantic? oh come on.

and little rat-dogs like that always love me.

i really hope the suicide by hippo was photoshopped, not a very flattering pose for either of them.

If you are doing everything right leading up to harvest you won't need tricks or gimmicks. If you look to the essential oil industry, you'll find lots of methods for increasing the production of essential oils in plants. You won't find anyone leaving their spearmint in the dark, that's for sure. Do repeated side by sides and get them tested by a lab, and let us know what you find.

It is not a trick or gimmick. There are a lot of ways to train your plants and make them do whatever you wish. You can flower a seedling or revert a flowered plant back to veg. Super cropping, scrog, other LST techniques. All done to stress the plant but make it stronger and more vibrant.

During flower THC is produced during dark periods. A good light timer is to increase to 13 hrs darkness at week 6 then 13 1/2 at week 8 on a 10 week flower.

I would not recommend going over 15-18 hours darkness as this will interrupt the plants circadian rit human. It more then likely will increase your THC levels dramatically but at a big cost to overall harvest. Your plants will be shocked and not respond very well after lights go back on. Loosing valuable growth time and depending on how your growing, Christmas tree, scrog, tying down, see of green. That loss of growth could be over an ounce because from week 6 on is where the bids really start to dense up.

Not to mention the loss of THC from the new growth. However if you go to 13 hours dark the plants circadian rhythm will not be badly effected and vigorous growth will continue and you will have 1 extra hour of THC production a day for 14 days then 1 1/2 hours the last 14 days. That's an extra 35 hours of THC production equally distributed amongst all growth.

Either way you go about it though it's not a trick or gimmick but an actual technique to increase potency.

I find that a lot of people don't know that when you chop your plant especially whole it's technically not dead yet, it would be in some front of Half Life half dead stasis for about a week, in which it will literally act the same way as it wasn't chopped.
Think of roses in a vase with water.

Meaning you don't have to give it 3 days of darkness before Harvest if you're just going to harvest it 5 days in dark area.
It would literally do the exact same thing, until it's completely dried up which takes about three days.

Are you saying that 3 days of darkness for a potted plant is the same as three days chopped? You believe that a plant is not changed biologically when it is separated from its roots?

LMFAO!!:)

If you want to increase your terpene's just use a blue spectrum light for the last 4 days before harvest to "finish" them off (This is backed by science)

I did this my last crop, and I am not sure if it made a difference. The buds felt stickier after the 3 days of darkness. I will do it again this time because as I said my buds were way stickier with resin but that's the only difference I noticed. The bud was great smoke so who knows. I think there is enough people in this thread to say it works for that to be our research. I say if you wont do it, you are closed minded. I say try it, see what happens. Be openminded to grow education as you will not get better unless you open your mind and listen to people who went before you and made the mistakes they are trying to save you from.
