does darkness before harvest ACTUALLY do anything??

Makes sense

Only thing that sways me towards thinking the dark period will be good is people saying the plant sucks the nutes back down into the roots so the bud won't taste harsh etc..

Harshness is less by not over-feeding, and goes away the longer you cure.

The most important influence on potency, aside from growing conditions, is harvest time. Let the plant sit in darkness for 3 days and of course it will mature more, it's been 3 days. Give it light during those last few days before harvest and it'll mature and grow.

If you guys can figure out how to turn off the sun for 24 hours...then this will be debatable. So anyone? Anyone know how to turn off the sun? No?

Furthermore your plant has been in flowering anywhere from 60 - 80 days. (1,440 hours to 1,920 hours) You have been on a 12/12 per day light schedule during this time. So an "EXTRA" 24 hours of dark before harvest is really only knocking out 12 hours of light. (please tell me that you are still following me)
So you couldn't build up a good plant in 1,500 hours...but it's going to be great by fucking with it in the last 12 hours? Does that make sense to you?

i dont buy into the extra dark doing anything but making you wait longer, but i can shut of the fucking sun on your plants(with a tarp) and guys do it alot in cali and here in mich on outdoor grows. there is a article on this in last months issue of skunk mag.they also use lights to water or " wake up" the plants for 5 mins. in the middle of the night, so they dont start flowering early.I say do like FDD and chop as soon as they are done so you can get ready for the next go around.I got 3 little shits i dont give a rats ass about so i think i will chop 1 about an hour after the lights go on, 1 ill give an extra 12 of darkness at the end, and 1 i will give an extra 24 of darkness so the last one gets 36 hours straight before chop. I bet the first one is gunna be the best for buzz and the last one will taste more smooth.they should be ready in 2 weeks.It's the little shit on the left. Ok i'm done jackin this thread

What do yall think about doing this w/ auto's? Also, on greenhouse seeds white widow...they suggest the last 2 weeks of bloom be in total darkness. This seemed weird and unnatural to me, but I'm no pro. Tell me what ya think. Thanks in advance.

If people say that darkness period doesn't matter why on some strains u should turn the light off for a week or 2 to get good resin prod.

now it's a week or two?

LOL HAHA hohoho, "now it's a week or two? " FDD you seem as shocked as I am that this is still going someone needs to do a controlled test and make it a sticky to end this X X. I heard that if you leave it in a dark cycle for a month you get 500% thc and 2000% cbn everyone leave your plant in the dark for a month after its done! Or just do it the right way and skip the bs that wont help at all.

well i am at the last of the second harvest---tri's are getting amber on the little stuff--looks to be about a 1.5 second hit. I am going to dark them out for 24 hours before harvest to see what difference in the tri's if any? I use a microscope to review and then harvest for peak and perfect ripeness. It seems as though it has been taking forever for the last little stuff to pack-in or harden up "not -so-fluffy" gonna cook with most of it. I have them outside they were on a 12/12 strict diet before I tossed them out there a month ago and harvested 2+ zips already off the girls a peice. And yes the days are getting longer and the nights are getting shorter and I turn on my back flood lights sometimes----I have found that once you force them into there flower cycle it's like trying to tell a woman to hold in a baby...K I ll let you know on the tri's ---next few days. I will look and note a bud before tossing in the closet and note the same one 24 hours later at cut time.

I guess next time i will veg with flourescents & flower without any light.

People are way too polar on this issue. This is about shocking and tricking your plant into doing something it wouldn't normally do. Of course no one is dumb enough to believe flowering without light will work, that is retarded. What people are talking about is 3 days tops, not 2-3 months. If it was getting a regular 12/12 cycle for a couple months and all of a sudden there was 0 light for several days, I imagine it would start to freak out pretty quick. Will that panic be more beneficial than continuing the regular light cycle for the same amount of time? Maybe it will, maybe it won't. I've heard this method of harvesting after 1-3 days of darkness works best on 'white strains'

I'm no marijuana expert, I've not graduated college with degrees in botany
But I'm pretty sure if you put a plant in total darkness for up to 3 days its gonna panic, and that panic will suck some of the life out of the leaves (if not most/all). What good will that panic do? Will it produce more trichomes? Will it ripen trichomes from clear to amber?*(I've heard a couple claim it ripened their trichomes a shitload) Will it add more cannabinoids, but not add any THC?

sorry johnny961, I'm not pissed at you specifically, I'm just venting in general over this topic
I'm sick of people acting like anyone who gives any thought to this is stupid and makes jokes about it'
again johhny its not you!

Buy great genetics...grow properly...finish properly.

One could in theory cover the plant up...

It's suggested to flower (12 hour light) this marijuana variety for 8 weeks, but 10 weeks will really give you the crystals you are after. Try to turn the lights off altogether the final 2 weeks of the flowering cycle- or at least down to 8 hours. This keeps the flowers from re-growth and stresses the plant into giving up its last drop of goodness as crystal to protect the flower!

From attitudes website for GHS White widow.

Lights off all together for 2 weeks or for 8 hours a day!?!?!?! Why such the contrast? How could 2 weeks in dark be better than 2 weeks of 12/12?

Is this still going on........LOL

I'm gonna go ahead and say that instead of using the time by leaving the lights off for 1 or 3 days or 2 weeks , you can make better use of the time curing it which improves taste, smoke and overall quality anyways.

Its mainly about the rumours started today turn into "fact" next year...by the end of the century people forget it was any different and assume the fiction is the truth...all because someone got stoned and thought what if...

Its a plant...plants all work the same...roots dont store shit at night. Show me a scientist who says that!

If you want to believe theres a way to make your plant more potent search for this thread:
"thc acetate psychadelic" - it will be obvious which result is the correct one....cbf linking for you ive put enough effort just typing this all again.

Theres fact, and logic and scientific procedure to follow, theres info on why you are doing it and what changes are happening....

Explanations on how THC and other compounds are changed between each other, and how to initiate that change ourselves, to manually convert the chemicals the plant uses to create thc, and make that change happen ourselves...all in a saucepan on your stove with water....

You couldnt be any worse off than letting your plant sit in blackness for 3 days or 5 weeks or whatever the magic number is now...

Im affraid i agree with the above about the storage in roots, im a noob but...i am a scientist. Plants respire in darkness using the glucose they have made and oxygen to create energy as we do. They keep the sugars where they are really or in the form of starch so they are close to the stoma for when the uptake of oxygen (in the dark) happens. Honesly i cant see what the darkness period would do, but the flushing bit yes as all the nutrients will be used and then NOT replaced during the weeks leading up thus leaving a chemical free (well the artificial ones) plant and as i can gather a better smoke . I dont claim to know much about cannabis itself it why im here but the chemical processes in plants, in general. Peace

Subd!!!!!!!

There are experienced growers who will argue this until they're blue in the face, it'd be nice to hear from a botanist. All in all I don't see 24-72hrs of darkness having any noticeable effect on THCA production.

If UV rays have shown to increase biosynthesis, an absence of that light could, in theory, slow production down.

I'd say stay 12/12 and, if possible, cut down before the lights come on.

so having plants in darkness is kinda like a self flushing? I mean if you flush regularly it wouldnt matter as much? But the darkness is just giving the plant time to get rid of even more extra "shit" stored in it?
