I can't believe we cant keep crap like growtradefuckfucks off here, my experiment is coming to a close, results: buds, good buds, sticky stoney and stinky, I think the plants had an increase from the light cycle, you'd have to get them going side by side to really tell, Did I cause the increase by some other variable? maybe is it worth the extra power? idunno did it affect potency? not adversly(gr8 smoke)
did it turn everything hermie? no
in conclusion, I would have to say that after flower set, the ammount of light can be extended up to 18-20 hrs for 2 weeks without any visible problems, who knows I might've really fouled this up, made some genes mutate or some other crazy shit, but it makes sense the plant would stay budding and just use the extra light to stack, the faq in overgrow claims 40 % increase, I believe thats possible. of course this should be taken with a grain of reality...im a stoner in the advanced stages of being stoned
