72 is way over kill. You won't need more then 24, I keep mine in the dark 12-16hours (depends when I wake up lol), and thats enough time to let all the nuts left be moved to the root system for storage.

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 seperated a crop of mature plants, harvested half of them and kept the other half in absolute darknessfor 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.


I figure Ill give it a try. On my last plant I just did 24 hours and that was some great bud. Ill give this a go and see if there is any difference

that last post is very informative. thank you for that. i had no idea before just now and i will plan on doing the same when mine are ready to harvest.

great info and great looking plants man:bigjoint::bigjoint::bigjoint:+rep for you

Could be, let us know, all I use the darkness for is for the very small amount of remaining nutes to drain from the plant and be stored in the roots.

If your looking to get more potency drop the humildity, this will get the plant to increase resin production, but the lights must be on.

I posted a little bit of info about the lower humidity, and resin increase. You can even look it up in Cannabis Culture, old Cannabis research books, ect..you can make your own opinion between jsgrwn's, and my own opinion.

I;m running 40-50% RH..How is that?

RH sorry I don't understand that one. If its something about humidity that 40-50% is still close to ideal for our ladies, down around 30-35% (thats the lowest my dehumidifier goes I want one that goes down to 20% to see if that changes it even better)for it to be dry enough for the plants natural instinct's of resin production to kick in... Light, and water are factors IN an enviroment. An enviroment is comprised of all living (plants), and non-living things (water, nutrients, light) within an area. I gave examples of enviroments, that dont have the PERFECT food, light, and water that you speak of...yet by some miricale our plants can still grow, hmmmm...

From the link I posted: My words, but I posted links to research that was done.
Just a little FYI I wasn't saying that going longer without lights would (as you so eloquently put it) "puke-up" resin, I was saying letting the medium get dry (there in the humidity within the room goes down), or drop a dehumidifier into your room to make the air within more dry will help with resin production due to the plants natural response to protect itself from dryness, and hot conditions (find Best of HT : Edition January, 09, then go to page 42). Ive yet to see a "nice" grow that only uses tap water, chlorine, and other chemicals within must do the plants loads of good without proper nutrients. I also am not saying let the plant go without water for months, the plant will NOT shrivle up, and die if it goes a few days without water. By the way water is not considered food or energy. "Water is an essential part of all process of plants. Through water, necessary minerals are moved from the roots to the parts of the plants that require them. Water moves chemicals from one part of the plant to another. It is also required for photosynthesis and for metabolism. It also helps cool plant surfaces (through transpiration).
Plants not receiving enough water will be lower in production of fruit, seed, roots and flowers. Without enough water, plants will close their stomates. This will result in leaf curling and rolling, reducing leaf and stem growth and fruit yield."- http://desertwaterwisegardens.suite1...ants_use_water
. To dumb it down water is NOT considered food, it is the way for "food" to be moved from the soil to the roots then to the rest of the plant. Yes its TRUE that the lack of water will slow in production (bud size), seeds (not looking for these), roots(its getting cut down in 1-2 days), and flowers (doesn't matter). If the "LAST 2 MONTHS ARE THE IMPORTANT TIME, NOT THE DAY BEFORE" then stopping water won't effect it either way then (except in resin production), cause I think that chopping the stem from the roots will slow these productions indefinately....
As for your UV-resistance comment... :smile: Ill post this link to actual research (read the "Enviromental Influence"), but since its on the internet (by regarded Cannabis writers) you will probably push it off as non-sence because it goes against your idea's...Here's the link, the arrows should help you find it>>>> http://www.cannabisculture.com/articles/2159.html <<<<

Now to dumb it down for you...In area's of higher altitudes (these are the Himalayas), and equatorial areas (sunlight is strongest here) THC potency is noticably higher, this means that the resin (has the THC) is in higher amounts...why might this be? Because there is more light intensity, and more UV light in these areas. The more UV the more resin, so that must mean that the resin is in higher amounts to protect the plant from the UV light (this is UV-resistance...how UV-sensitive equitment is used to find plants that are hidden below forrests, or olive trees). I think you were thinking of them looking in open fields for the cannabis plants, but that would be dumb (oh wait who are we talking to here).
Here's an article from Ed Rosenthal ( http://www.cannabisculture.com/v2/articles/4351.html ) stating resin as a defense from UV light making it a very UV-resistance plant.
Here is an article from a veteran grower stating his use of MH lights (which product more UV-light then HPS) and how the potency is increased with UV-lights. It is againt stated how areas of higher consentrations of UV light (mountains, equatorial areas) offer higher potency levels of cannabis. >>>> http://www.cannabisculture.com/articles/2696.html <<<<

"the only really sun resistant plants are found on the floor of the rain forests, these plants have a red color instead of green."

HAHA you mean the rain forest floor that very light light penatrates? Have you ever notice the colors of the leaves changing? All plants have the red, yellow, orange, ect. colors in them, so saying that a red plant on the floor of the rain forest is the only sun resistant plant is nieve.
"and as far as the sugar you use, this is a carbohydrate for the plant and can be used or not but should be used in the final 2 weeks."

Very good Sucanat is a carbohydrate. Why only the final 2 weeks? Have you actually used this to know that it should only be used in the final 2 weeks? It is fine to use this or other "boosters" such as Sweet during the flowering stage just as long as you take into account the extra PPm that these will add with the rest of your nutrients. So if you have the ability to back the nutrients off +/-100 PPM roughly your PPM will stay fine with adding these at the recommended levels.

I Just chopped this plant down. The 72 hours did seems to increase the resin on her quite a bit.
It makes sense if you think about the fact that THC is degraded by light. The potency of a plant changes from morning to night. Since light degrades thc is pretty easy to understand how the plant would be the most potent in the morning(right before the sun comes up). This is the reason the 72 hours of dark works so well
It doesnt degrade the thc for 3 full days before chop. Think about it

was it just me or did i see white hairs all over that girl?? like, all over.

im no expert, but from what i do know id have said let it go AT LEAST another 10 days. you had new pistil growth all over the place. oh well i guess, enjoy

it was ready lol thanks for the input though. no new pistil growth and I gotta say thats amazing that your getting all that from that picture. The resin made it so I couldnt get a decent shot. But right on
Heres one of the buds
