Sir420 here .. I see plenty of post seeing ppl hit 14-16 oz in 2x4 space. But how tall are their canopies??? 8ft lol or 3ft??? If I can figure out how tall of a canopy they had , then I'll know exactly how much wattage to put in a given area to match that 2x4x? ..but stacked vertically I can put the exact amount of led & wattage in a given area & then stack em by having a DiY tube in the center of every vertical canopy ..
