I seemed to have 5-10% amber trichs for a good 2 weeks and they stayed that way until I just couldn't bear to wait any longer and chopped em'. Great smoke.

So Weez,? How do we determine when to harvest under LEDs? Aside from the obvious... growing the same strain out a few times to guage it. :smokin:
the longest i have gone is 63 days of flower under LED's and i have about 30-40% amber trichs...are you growing some wild sativa?

i'm not Weez but i couldn't help but give my .02 ....i do everything from clone to finish under LEDS and i am finishing faster...i used to run everyting 70 days under HPS and my 63 day LED grow is narcotic!:stoned:
