Dont expose them to light!

If you have to go 4 to 7 days without a grow..do that rather than wreck your work.

Its not that ll have to go without a grow..I have many still on the way..hence my problem or I'd just shut off the lights.. but by putting them outside the room I don't have the exhaust carbon filters and etc..either way I lose.
You're probably right tho

You carnt use a garage or shed? (i use my shed for large amounts)
I use a cupboard in a spare room for drying small amounts and it doesnt stink the house out.

i find that most of the studies that people are still quoting were done at least a decade ago, some as much as 50 years ago. the greek study being quoted above is from 99.
i'd really like to see some current studies of new strains that are much more potent than those grown 20+ years ago.
places like NIDA do studies...how can you expect a place named the Nation Institute for Drug Abuse to do a fair, non biased study?
is anyone aware of a non-govermental institute doing fair, even handed research thats not aimed at demonizing marijuana and its users?

I agree that we need more hard data, more science in general and specifically more studies on cannabinoids and their development over time in relation to conversion, oxydation & decarboxylation etc.
However, I do believe that we are seeing an increase in these sorts of studies, but since the nature of scientific studies are very specific, it's hard to get exactly what you want.
And much of the science being done on Cannabis and cannabinoids is rather elementary if you will, not that it's too basic or useless, but we haven't had a free flow of Cannabis research and science for a long time, we still don't in much of the world, and there is a hell of a lot of research to be done on these subjects. Most of what is done is studying the effects of the biology of the receptors and how the human body reacts to specific compounds, not broad studies on the cannabinoids themselves and their development.

I found a really nice study on the difference between vaporizers, including one I own, which is how I found it, and I must say that it's nice to see studies on cannabis, cannabis products, cannabinoids and tools are becoming much more respected and prevalent in the scientific community.
The study I found on vaporizers and how efficient they are; http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0147286


With regards to your question, I think there are a lot of institutions and organizations who carry out great objective research, but if you are looking for hard science the best place to look is in scientific journals.
Much of the research being done is very specific though, and you'll have to spend a long time researching all the different studies to find something that resembles the holy grail of the study you are after, which I presume to be something like; "In vitro & in vivo quantitative analysis and validation of cannabinoid development and conversion in Cannabis".
A study like that does not really exist at this moment, hopefully it will in the future.

My plants are always frostiest after a few hours of lights ON. I always harvest before lights come on, and preferably after 24h in the dark, but the harvested stuff is never as frosty as the samples I take with lights on. Do the trichomes fill out with the starches etc. that people are trying to avoid?

my previous harvest was some of the frostiest stuff I've ever grown, but after harvest it seems like all the trichomes just disappeared and I don't handle the buds rough during harvest.

First, thank you for the thread.

Do you believe in an extended dark period before harvest?
Do you believe in flushing?

Haha. I know you don't @RM3.

Just trying to get more opinions. I'm not doing a flush. But I haven't looked into the dark period thing just heard ppl saying.

So do you think I should just chop them right before the lights come on?

Does that even matter? Because it would be nice to have the lights on to see better...

I chop durin lights on but I think everyone should try things and see for themselves

I guess the idea is that lights on draws nutrients and water into the buds right before you chop. But even if this is true it should be negligible anyway right?

I don't have the latitude to just try shit right now. It's profit or loss . Continue or fail.

If I make it then next grow and thereafter can be experimented on....

Ive never flushed on past grows but this time Ive got a plant going a little longer than i expected so I'm using it as an oppty to test out 2 weeks water only. I have zero experience with this strain so no real point of comparison. On the other hand I do find that there is a benefit to a period of dark before chop. I was very skeptical for a long while until Spurr over on TLG suggested I try it out.

This is 8ballKush day 55. 12.5 /11.5

Why 12.5?

I'm running 12 12

I was copying from captain morgan and church haze and others. We use 730nm @ lights out to extend the perceived dark period. Im switching them to 13.5 / 10.5 today. So i do a few weeks close to 12 12 then add longer lights on for like 3,4 or 5 weeks then back closer to 12/12 to finish.

Yw, glad you found it helpful.
No I don't believe in turning off grow lights to 'push out more trichomes' or whatever it is people think happens by doing that.
It's an unproven step that makes very little sense.
I would obviously change my view if I were presented with proper evidence.

Flushing in general can be helpful, if you understand the difference between 'flushing' and 'pre-harvest flushing'.
Flushing can help clear a growing medium of a build up of salts, or correct errors in pH values etc.
Flushing is used by most growers during a grow, but in particular it's useful for new growers to correct errors.

However, I think you are asking about pre-harvest flushing, which is an unfounded procedure that has no basis in science and is myth based in it's supposed advantages. I've heard everything from clearing out chemical taste to pushing out trichomes, none of it has been proven. I've written extensively on this subject, but just to mention one fact that utterly shatters pre-harvest flushers fantasies; Nutrients aren't stored in the calyces, there is nothing to 'clear out'. Furthermore, nutrients are nutrients, whether synthetically manufactored or organic, plants cannot distinguish between an organic or synthetic fertilizer. Thinking that you can improve yield or taste by feeding just water to a plant is wishful thinking at best.

I would not recommend that anyone should deprive their plants of nutrients in the most critical phase of growing; late blooming.

Yeah. I'm done with worrying about it. Can't find any science. It's just that every tutorial from high times to growweedeasy says to flush.

No flushing for me.

Been waiting 12, almost 13 weeks on this blue dream sativa, smells like turkey ginger, its going to be great :blsmoke:
I've been telling myself that I'll chop tomorrow every night for the past 3 weeks with my nails in my thighs, but I've waited watching it get milkier fatter purplier and stinkier than the times I chopped at week 9, bit anxious but the patience will probably blow my mind, CBN could help too. I'm so excited im probably going to chop in a few hours if noone relpies, if anyone thinks another day could help pack extra punch please let me know I think this batch will make the other batches uncomparable, Based on what I see most areas are (I think) 10% clear/milky, 80% milky, 5% milky/amber, 5% amber. some of the milkyish look clear to me cause i see some clear trich heads with tiny amber dots. some buds with shade patches didnt get as purple are more like 10% clear 10% clear milky 79% milk 1% amber. 2 weeks till lift off
Update: I just put her in so that she'll get 5 more hours hps give 12hrs darkness chop then try leaving her dipped in a cup of water for the first day to try to prolong drying a few extra days this time

yeh well...amber means it's degrading fast...plus that couch lock is more like drugged than being high...I personally don't wanna be knocked on my ass unless I really have a bad medical condition that has me in lots of pain which I don't.
I like to just feel nice and high of varying plateaus ...just not melting into the floor. I'll save that for shrooms....lol. I got Barney's LSD ready to harvest in a week or two so that should hold me over on a new plateau for a spell...HA!
I'm waiting for the trichs to just get to one or two amber and then I'll water and go dark for 24 hours and chop in the morning...after I say a prayer over them first....:leaf:..ha

Hey fellow cannabis goers. How does this look. I picked 1 stock trichs were a little cloudy and 30 percent red hairs. What's your opinion strain is white widow. Thanks everyone
