I really doubt that man, you can keep em green but then you end up with all kinds of nitrogen in your buds and more chloryphyll the chloryphyll is a major factor in what makes bud harsh when you smoke it. That is what curing is for because it breaks down the chloryphyll but what you do when you pick your plant with green leaves is make it have to take longer to cure properly because all that extra chloryphyll you made it have by adding more nitro than it needed.
The reveg thing that cruz was talkin about most definately works i've done this. It's good to leave the big fan leaves if you can however not completely neccesary and start feeding nitro again after harvest. Make sure you leave some small fluff nugs on the bottom of the plant "to unravel" so to speak and reveg is no problem with enough light because it has such a large root system and not much to support anymore.
So i guess in a way that is increasing the yeild of the plant because you use the same plant twice... but no potency is not affected in any way but a negative one. You wont notice it the first time you reveg but the more times you do it to the same plant it plays out. Loses the ability to produce after reveging a few times.
Sorry to jack your thread cruzer just wanted to try and clear that up a bit.
Ahhh ingenious light mover =) what do you do about light leak comin from inside there during the early morning and night hours when the light kicks on?
it is very possible! alot of ppl on this site 'keep em green' and in fact the yellowing during flower is not normal and u will increase potency and yeild if the plant is kept green throughout its whole life
