my take on leds so far is that the buds themselves seem to be of better quality than my runs with the same plants under hids...and in general my gpw is higher under led but not by enough on average to overcome the wattage differential....but that said it's pretty close and i'm reasonably sure that i could close that gap with better canopy management...i'm pretty well convinced at this point that at least for the hot months of the year led is a far better choice for me...
