fine then, ur not listening, thats fine, ur clearly a cock, i've already proven it to you, this is how thread arguments start, go back and re-read what i've said, if u dont follow then its going over your head. i'm not going to re-hash shit till i'm blue in the face, ur not worth my time. troll

as for the chap who asked originally, as u can see this is a topic of some contention. if ur mind hasn't been made up, try it for yourself, its the only way you can know what works for you!! good luck dude. unsubbed
You are correct I am not listening to you, youre full of shit and have little to no experience w/ growing cannabis.

Harvesting in the morning ensures that your plant will be at peak THC content, as cannabis has shown THC fluctuations peaking in morning and dropping during the day. Some growers leave their lights off for several days before harvest to increase potency. This seems to have some scientific validity as light has been shown to degrade THC, hence the morning peaks. As light is the degrading factor and the plant still has the ability to manufacture THC during darkness, leaving the lights off for a day or two before harvest likely utilizes the plants stored potential for THC conversion without any opportunity for it to be degraded into cannabinol (CBN) and other breakdown products.

during the day ur plant will grow and at night it will work on its root system, this is why even for autoflowering plants 24/0 isn't a good light pattern, even tho auto's can handle it, u need healthy roots as much as you need a healthy green lookin leaves up top.
Regular cannabis plants can handle 24/0 also, they are a c(3) annual. Only needing a photoperiod reduction/change to trigger flowering. And plants grow both foliage and roots, lights on and off. The roots at night and foliage during the day thing is pretty much a wivestale....

Once my trichomes have turned approximately 20% amber, I throw my plants into total darkness for 36 hours before harvesting them. I can't say as I've noticed an increase in resin production, but an extended dark period does allow your plants to use up stored sugars and will quicken their ripening. The cooler temperatures during this dark phase also really brings out the color and fragrance of your buds. Just make sure they are placed in a dry place, and have a fan circulating in the room.

I keep mine in the dark for the last 3 days. My Widows showed definate improvement in the trics, and I've been doing this for 15 yrs. I'd like to think I have somewhat of a knowledge base. Also, plants don't need to drink so much when in the dark, so there is less water weight to have to deal with, thus reducing the risk of mold during the drying and curing process.

Agree or not, don't care. That's just how I roll :;.

Giving an extended period of darkness deactivates the green chlorophyll which is active only during photosynthesis. This is to minimize grassiness. Ta da!

It takes anywhere from 6-16 (depending on strain) weeks for trichomes to fully develop and mature naturally, even IF a plant could produce a fully grown trichome in three days, which is very hard to believe in the first place, it would be clear and contain nearly no cannabinoids.

i just posted this earlier today fir some dude asking why his buds had a weak smell after harvest -->

through the lighted period, the raise in temperature and especially high heat, evaporates the terpenes that are in the thc glands. terpenes are what give you your smell and are most abundant at the end of the dark period.. to be used up during the day. the plant is designed (evolved) this way to use the terpenes to ward off insects.. or attract animals to eliminate pests. interesting indeed
so my advice would be to chop after a full dark period when the terpens are at their peak.. or even a full 24 hour dark period if possible.


the deal is this... it cant hurt to put your plants into 1, 2 or even 3 days of darkness before harvest.. so why not do it if possible? its basically putting the nail in the coffin and pushing the flowers to the max of what you're gonna get in terms of production. even if you get 1% more trichs it would seem worth it to me.

either way people are gonna believe what they wanna believe.. and thats fine :)

Cheers :bigjoint:

This is my 2nd harvest and I gave my girls 48 hours of darkness before harvesting and got good results of course I don''t have anything to compare it with so I don't know how much good it really did but I was happy with my smoke.

I've read recently of a cold water flush during dark (Weed World Issue 96). It was an article from a med grower (I want to say in the States) but he had claimed they do 3 days of dark prior to harvest but also flush with cold water in the last 3 day dark period. I think he called it cold water shock or something.

does resin production stop as soon as you chop the plant??? if not then when you dry in the dark before the cure does that increase resin glands too??? cause i'm harvesting 3 plants at different times.....so i can just turn off my lights for 3 days.

I am going to try it...I'm just going to put a box overtop of the one I want in the darkness...the strain description for this strain says it makes a difference....so we'll see...

I was thinking you all should try leaving the lights off for a week and a half before harvest. Think about all the new resin glands you will get.

I've onl done two grows but I had 48 hours of darkness before each harvest and I was pleased with the results. But then again I don't have a harvest to compare it to.

regardless of how many grows i've done, if i put a plant in the dark for 3 days its gonna do what its gonna do. how many grows before my experiments valid ?

why you trying to shoot me down? is your self esteem tied to this in some way? we're all here to talk about what we've done and learn.

you've mentioned scientific facts that ur basing ur opinion on, care to share the source? you can search for people using UV on this forum and find shitloads yet the only time this topic is being discussed its iffy mythy.

bricktop posted a study saying that theres an increase but its strain dependant, this ties in with my opinion that i didn't notice much if any difference. i'll take proven specific tried and tested methods rather than some that are sketchy at best[/QUOTE

As with any experiment more than one case study is needed so the fact that you only have one grow is completely relevant, I would say 5-10 (exact) experiments. Just saying its not a self esteem thing.

Okay, so I am going to flush for a week, then place in darkness for dankness, nice Dolci. That's a double negative, oh nooooooooo. lol
Anyway, I am trying to see if I can get my girl to use up all her chlorophyll while in the darkness. I think I will try 24 to 48 only in dark.?. ve shel zeeeee
Sooooo, I will let ya all know. Starting darkness Thursday or Friday based on trichs

If three days in the dark makes it better, perhaps you should keep it in the dark for a few weeks. Think about how good it will be then.

some cultures darken, and even bury their plants for longer.
I''ve tried on a couple hundred over a year, darkness for three days, then two, then just 12hrs, then settled on harvesting weekly before the lights come on, from the flush tray, with no watering for a day. not scientific, but darkness requires another room, and thats costly in a rotational garden, and did not justify it's practice, here. I do use a 1000 watt UV bulb to deliver uvb and uva to finishing plants, and they are much better than without. Lab shows more terpines, but thca/cbd/cbn profiles were similar.
After genetics,nutrients, climate control/quality, the best investment made was in a water cooled propane powered c02 generator/controller set up. o2 depletion sensor,water temp sensor, tip sensor,overheat sensor, and prolly more. It increased my harvest weight by 30%, and flowering cycles decreased by 10-20%. It was a real no brainer and paid for itself in one month! costs 20 bucks a month to fuel, never failed.
