Less light = more flowering?

bro54209 · Feb 20, 2016

If i could put a plant ontop of the aircooled hood reflector would it help finish off the trichomes? I heard that turning off the lights for the last 36hrs of flowering increases trichome production but im do a SOG and think keeping that at 12/12 would be good but perhaps putting a finishing plant its last day ontop of the reflector (it will balance and wont burn) its still bright from the mylar reflection but will keeping it out of light directly finish it off better than to finish it under the light?

I think that's an unproven tradition, go with finishing under lights until you find a careful experimental test.
Increase trichrome production with the scientifically established method - add UV lighting

Some people switch their HPS for an MH for the last ~2 weeks of flowering for this reason. MH bulbs give off much more UV.

Good point on UV trichs are suppose to help the plant protect from them, in that case Im putting it down by the air intake where its brezzy

Try it and find out. I'd say you'd get less than the ones under the light, but I'm no expert.

fuck that shit turning off lights just puts them to sleep . you need to put in a mh bulb last week or better yet a 10000k purple bulb about 45 bucks mh. works very well .

I put the plants in a bag and carry them around with me for a couple of days until harvest.It's kind of a pain in the ass but I get 50% more this way.

Ermmm thca is converted to thc via decarboxylation man the actual growing girl has very little thc I'm comparison to thca...

Sorry you are correct, there is little thc but the more thca you can get the greater the carboxylation of thc upon harvest, forget why light is an inhibitor but been a while since i looked at canibinol chemistry.

Maybe you can explain the reason behind the dark period before harvest science and remind us all....

Shouldn't this thread be in the "advanced section" where the really smart people can discuss it

! To OP try it and see what happens, perhaps you can put this age old question to sleep

I think its been answered in many threads why people opt for a dark period before harvest time, didnt think it was an age old question just a small bit of scientific reasoning and im curious to reaquaint myself with the answer again.

Its cause in the dark period their nutes go back into the roots, and when the light comes on the nutes start going back up to the leaves. You chop em b4 the light comes on so that they cure a smoother burn with less nutes than you would if you chopped em when the light came on

This sounds highly unlikley :-)

Ummm well I was kidding about the smart people thing. But no it hasn't been answered that I know of but if it has and It works I never got the memo lol. Yes people opt to do it but does it actually work? And as for scientific results again missed the memo. Not putting your question down though, if your curious try it and see, can't see it causing any issues at that stage in its cycle. It's like most other things canna, lots of differing opinions and really the only way is to see if it works for your setup, I think it's myth myself but have never actually did a controlled side by.

Firstly id say the difference would be small even if it made a difference and secondly idnk what your on about, there is a myth that more trichs happen from an elongated dark period but then theres studies of thc etc (not trichs) which show that marijuana harvested in the morning is more potent than that harvested late in the afternoon.

I doubt the idea could be easier as Thc is refuted to act like sunscreen to a plant (or you wouldnt be trying to induce it with uv-b light). Light degrades thc so theres probably more there in the morning than night.

The whole thc thca canibinol chemical cycle is what i cant remember, didnt think it was that complex to anyone whos ultimate goal was to grow marijuana.

Im not going in about anything lol. If you have scientific studies that show this please post link. I'd be interested in seeing it proven that potency changes in a daily basis and from morning to night.

I've done 72hrs. The plant dried up and died. I usually do at least 24-48. It seems like plant gets almost oily with resin. Never tried a heads up comparison between 24 and 48 or 0 hrs of dark . But have tried all 3 and in my experience the dark period plants have more or stickier resin.

shadow22 · Feb 21, 2016

don't make sense to me lol I agree with seeing a side by side imo.

What that potency changes on a daily basis....?

Try the reason why most growers harvest in the morning or before lights on not at the end of the day.

I harvest before lights on so all plants have had a dark period prior to the chop, no reason it cant be extended 12/24 hours under the same reasoning that buds are more potent after a dark period.

A 72hour dark period seems excessive, maybe chlorophyll would start degrading here or some other thing but thats probably not thc related.

But do most growers harvest in the morning? Again I'm not arguing with you, just asking for some links. I've been doing this for a really long time and I harvest when I can. I typically used to harvest at night outdoors so the boat wouldn't be seen full of pot lol. But if I'm missing out I'd like to know. Seems a little bit like bro science until I see the proof.
