36 hours maybe, not a week. There have been some laboratory studies done on it, i think one said that it found a 30% odd increase in THC levels after the dark period, but i have never personally noticed much difference from one over the other when i've tried in the past.
how come?
i have super haze and purple kush right now...
dont seem to find it, any idea what was the topic?

Are you discussing cold shock?
When you take the plant and give it cold water, then put it in darkness for three days before chopping.
Supposedly this makes it flower more and trich's increase but I tried it, and firmly raised the b/s flag.
Soil was wet, plant took longer to dry, and just did not seem right.

i believe bricktop posted testing on this method i did it and its not to do this as mentiond above Supposedly this makes it flower more and trich's increase but I tried it, and firmly raised the b/s flag.

pretty simple really just think when your in flowering you go to turn on your lights you sure can smell your plants right ???
thats because THC was being made lights off period
now when you go to turn off your lights you notice wow that smell isnt really there thats because when light on period THC is vapourized burnt up in a sense lights off your plant will replenish all the thc that was lost during light cycle and will make more THC to account for the loses and so on as you flower does this make sense to you ????
i also read that if you decide to shut lights off prior to chopping you need to keep it off no more then 72 hrs an no less then 72 hrs
so as brick top mentioned in some thread its 72hrs of total darkness keeping temps in the 60 degree for best THC percentage anymore you break done the THC and then it turns into another cant remember what it is called but i tryed it and was very impressed with the results and have implemented it

that's my understanding as well.....what you've just explained makes sense when you think about it.
and it seems like most here say it should be no more then 72 hrs so that's good to know.
just shut everything down last night after realizing i had the lights on for 24hrs [my bad, forgot to switch the timer back on] so
it'll be off for the next 3 days then.
besides, nothing wrong with saving a bit of energy if you can

It supposedly works better in the "White" strains.
"The Stichting Institute of Medical marijuana (SIMM), the first company to sell marijuana through the pharmacies of Holland, has been investigating the medical possibilities of cannabis, together with TNO laboratories 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 an increase of THC of up to 30%, while CBD and CBN remained the same."

exactly i flushed week before i went 72 hrs off during last week plants uptake from soil was litterally nill i mean after 72 hrs my soil was still like a watered night before but in reality i am sure they took some but over all pots were wetthat's my understanding as well.....what you've just explained makes sense when you think about it.

i think its always like last 2 weeks that its killer i mean you just want to end it but i find its the most crucial time off your complete grow thats deciding its time to harvest last 2 weeks is when weight / taste and everything else is there cut to soon you lose lose
drying / cureing all these is what counts
fck all to grow weed but keeping it alive giving them what they need last 30 days of flower is what counts
you work so hard tending them would be a waste not to get full potential from your grow

Lights off for 2 weeks before harvest, go to the Attitude Seed Banks site and read Dinafem Seeds White Widow description!

lights off for two weeks before harvest..... come on people... really? They're your plants, and you're free to do what you'd like. But have you heard of people doing this for ANY other commercial vegetable or crop?

Yea 2 weeks seems a bit extreme. I'm growing Nirvana's white castle right now ( White widow x Ice ). Supposedly works better with white strains. I Might just cut my lights down to 6 hours the last week.
