Has anyone ever heard of letting the plants sit in dark for 24 hours before cutting them down? Does anyone know the purpose of this and does the same thing?

Thanks!

Google is a wonderful tool.
So is RIU...
I've heard of it, and I do it too, they say it helps with trichromes, I honestly haven't been able to tell, so it's not like 24 hours of darkness is going to transform your buds into giant trikes, but if nothing else, you can add some color I just put them in the dark, crack open a window to let the cold air in and bring out the purple in my buds, I know for a fact that works(strain dependent, obviously)

its preference, if you want a scientific answer then no it doesnt do anything...some will disagree, some will say theyve done it and noticed a definite difference, ive personally tried it and it did nothing for me...some say its even strain related more so than anything...but in the end, there is NO scientific, peer reviewed concept proof that this works...maybe try it and go with your own exeperience...if you see a difference, than by all means...it wont hurt anything really. good luck
 
I think it does nothing as far as plant potency. I doubt there is a single person on this planet who could tell if you put your plant into 24, 48 or 72 hours of darkness. Maybe it gives better visual appeal and thats a huge maybe. My guess is that most growers are use to looking at their plants a couple times every day and if you turn out the lights and don't get to see them for a day or two, when you do turn the lights back on to harvest it just seems like the trics are bigger or frostier due to you not having seen them in a couple of days like you are use to.

I did some Google research that brought me to some different post on RIU lol.. From what I read a lot of people actually do 48-72 hours.....

If it helps with drying and what not then I don't see a reason not to do it... Surprising there's no scientific evidence... Where are he scientists?

Are there any issues if you leave the plants in the dark for too long without hanging them?
hi breeze, im glad youve done some research on this subject and have decided to go your own route, that is understandable and I resepect you for it, whether the answer is right orn ot.... although there isnt even 1/10th of the studying being done on MJ and MMJ (medical marijuana) there is some goign on and i am sure thsi has been tried in a scientific setting before (although im not positive...things like this are more subjective than anything so in the end its a hard thing to prove if it really does work, alot of it has to do with opinion, but i as i stated in my preivous post, you will not find much scientific, PEER REVIEWED (most important) evidence on this matter and if you do find supposed 'scientific proof' i ask you this, PLEASE be sure that what your reading has either been proven by numerous and large groups of scientists or corporations/organizations (which is pretty impossible in this industry)...and if not then please make sure the evidence is studied, proven and reviewed by other scientists (peers) ...if something is truly scientific it should be able to be set up in a experimental situation using the scientific method (hypothesis etc) and proven. It should be able to be replicated many times over by numerous people and/or scientists, not just people who want to sell or make money from it, or anyone else who may or may not have a conflict of intrest in the matter...these things are very important when proving something and should always be reviewed carefully and taken into full consideration even more carefully....either way, good luck in your endeavor and adventure friend, may you find a pot of golden green bud at the end of your rainbow :)

The head dude at my local hydro shop told me he does 2-3 days darkness to allow the oil production to "recover" after it has been reduced by the heat from the HID bulbs. He told me that if I were using LED's the dark period would not be necessary. I don't think it makes a night and day difference but time to re establish oil production can't hurt.

Yes, people will do that, not sure if it has any value but likely wouldn't hurt.

I believe most would agree that you would want at least 12 hours of darkness before cutting....but I'm sure someone will disagree

Someone always disagrees, no matter how much sense something makes.

12 hours dark is just enough time for the leaves to re-mobilize all their starch. Then when you chop, the leaves will have no more starch to re-mobilize to the buds during the drying/curing period. The objective of a good cure imo is to burn up all the starches and sugars remaining in the product before smoking.

I recall an article from one of the canna magazine talking about the dark period, it even made a claim that 10 days of darkness prior harvest can increase resin production, or something like that. Idk about that, just because I would hate to spend the 3 months or so to bring a plant to harvest and lose it to bud rot. Anyways, more importantly it said something about its best to harvest after a dark period, something to do with the thc recycling during the light period. The words used in the article did little to actually help me understand more on the subject. It really just stated some thesis statment. So who knows? A question I have been waiting to ask is, what if you have a scrog and harvest tops first? Can you do 24hr dark and then resume 12/12 with no effect to the unharvested buds? I remember a post a few months ago about a guy who went on vacation, like week 5 of flower and just shut his lights off for like 5 days and then just resumed. I think everything turned out just fine too.

It would not be difficult to stagger the harvest.
Chop down and take out one plant after 12 hours of darkness
start the drying process.
Chop down PLANT 2 after 24 hours
Plant 3 after 36 or 48 hours....
and so on....
Observe the appearance of the plants, the buds, the trichomes,
the fan leaves, the trim, the branches and stems.....

This experiment would be more useful if 3 or 4 plants could be discontinued at each stage.
That way it would be less likely that an anomalous plant could throw out the data.
ALL the plants would need to be identical genetics (clones)
grown exactly the same way (light, nutes, temps, RH....)
Only the final post grow dark phase could be different.
