Before harvest tips?

[blacknhlpower]

Hey guys, Sorry I have had a hard time searching for the answer but can u recommend any tips to do right before harvest, like day before? Should I give it an extended dark period? I'm harvesting on tuesday. I already flushed it with straight water a few days ago.

Thanks in advance

Good question, i've been lookin for the same answers for future reference. Goodluck! Burn this one down while we wait

24 - 48 hrs darkness, then.... chop, trim, dry and cure.. if curing is not your thing.... Then I guess it's straight to medication time..

Peace and Happy Growing

one tip is dont get impatient
i dont do the dark period some do some dont i dont

well, a couple hervest tips from me, but u might be too late for them tho.

2 weeeks before harvest (the flush) use mollasis for a supplement feeding nutrient, u can also switch to MH (if u got one) these 2 things should help feed during the flush and build frostee trikes....heres a pik of a plant grown under nothing but MH, due to the high levels of UV in the bulb it creates a MUCH more frostee bud.

as for 24 hr DARKNESS before chop....makes no sence to me.

The 24 hour darkness before harvesting is so the nutrients in the plant are not harvested in the bud. when the lights are on (photo period) the plant is sucking up nutrients and running them all through its internal system. when the lights are off, all the nutrients return to the root system because the plant is not feeding at that time. allowing 24 hours of no light before harvest will give you a much cleaner and tastier smoke. hope this helps helps. Good Luck!!

From what i've read the darkness is more about THC production then cleaner smoke. THC is destroyed during the day by lights and at night is replaced plus a little bit more. By have 24-72 hours of darkness before harvesting the plant never loses THC during the day due to the lights being on but still produces THC to replace what would have been lost + a little extra. Studies report 20-30 percent more THC from doing it. Do a search and you will find some of the studies on it. I think the cutting the nutes is what you are talking about 10potrma as that is what supposedly leads to a cleaner smoke. I haven't heard about switching back to a MH during the last 2 weeks of flowering but thats interesting since ive been reading about the blue end of the spectrum helping with THC production.

thats wat the flush is for too.

i have done ALOT of reading my freind, and ANY PLANT going from 22% THC to 50% in a matter of 24-72 hours is just UNREAL.

Single ended Metal Halide HID lights give off almost no UV rays.

"Do metal halides need a UV shield?The outer envelope of a single ended metal halide bulb filters out most of the UV rays emitted from the arc tub. Double ended bulbs on the other hand do not have an outer envelope to filter UV, so it is necessary to use tempered glass to filter the UV rays."

I'm with fuzzy buds..
24 hours darkness doesn't increase genetic potency (thc) it just helps the plant ripen a little faster..
simply curing it on the stick prior to chopping down.

Flushing is your best method to ensure that you get the best of what the plant has to offer..

I believe all the reading you are doing about thc levels is actaully about THC potency not amount of THC...........just my 2 cents

24 hrs of darkness causes it to produce more resin doesn't make it more potent . Never heard of switching to mh . If anything that would be a lack of the correct light (red) mabey cause it to produce more resin . Mh dont produce helpful uv rays gotta use cmh for that with no glass in your hood .

I don't disagree that that sounds absurd to see a 30% increase but I'm not going to pretend like im qualified to disagree with a legitimate scientific study. I've heard of people that do and and say it did nothing and of people that do it and swear by it but ultimately those people don't set up a sound study of it to know for sure. That is also not to say that every strain would exhibit a 30% increase just that some do. But hey why not give it a shot it doesn't cost anything and even if it increases THC levels by 2 percent is worth it in my book.

Check out this thread for more info - https://www.rollitup.org/harvesting-curing/374589-harvesting-tips-tricks.html

Here is a little excerpt from the thread that talks about what im saying:
"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."

Some people claim if the crop that was harvested first had been allowed to grow for the same additional 72 hours that the other crop that was kept in total darkness the THC levels would equal out but I do not believe that would be true, not given the fact that THC works as sunscreen in trichome heads and a small amount is lost each day, then replenished at night plus a small amount more. There should be some net increase with an extended period of darkness. Possibly not the full 30% that was found the way the test was performed, but there should be some increase.

the potency is due to the ammount of THC....so wat do u mean?

correct light? never heard of it. preffered light, YES. but NOT NEEDED, look at LED's they use a mix of reds, blues, purples, all kinds of groovy colors! they r new technology, but wen has technology really let us down?

I have seen large industrial grow rooms drying their buds right next to the grow area. I think the drying in light and dark stuff is a wives tale of pot growing. I dry with moderate light and have no problem getting stoned. Taste is overwhelminglyly great with many of those little darlings... well you understand right?

Egorleski, if you say so brotha man, i never noticed the difference. LoL.

as we have been saying all throo this thread, light DEPLEATES THC, meaning goes down. try drying in COMPLETE darkness, and at a cold temp (70) with low humidity, try NOT trimming the buds before u dry, just take the fan leafs off and dry it. lemme kno wat u think then. your dry will take a GOOD 8 days at least then try it out and hit me back, ill be here.

Choosing the preffered light would be a CORRECT choice . Ceramic metal halide lamps increase resin production .Check out the color spectrum on them . There are many studies in progress on RIU using lamps that produce UV .

 

[FuZZyBUDz]

Preffered=RIGHT CHOICE?

i preffer to shoot first, then ask questions....(not really, just an example)...does that make it right?

no preffered is for the one "who wants to be like everyone else", i DONT want to be like anyone else. so for that matter, DONT use MH in flowering, dont get a awesome trike build, do u want piks of my side by side????

i wouldnt come on here barkin BS man, not wat im about. these are TESTED (BY MEEEE!) facts. i havent use CMH, i rock digi ballist, but i did some research on high pressure metal halide bulbs tho, suppose to be a step up from CMH, comes in kelvins from 8000k to 20000k, that should get some resin to build.

but YOU need to open up your mind and ACTUALLY TRY SOME SHIT OUT before talking about it, its not good to run off he said she said.
