. Yes, if you fill that area with budsites with scrog or lst, supercropping etc., then 2 oz. per harvest is about what to expect.i got a new cab thats 24"x12"x28" ive got a 70w hps in it now and the temps get up for 90 sometimes. what do you think i could yield with a 63w LED light in this box? i want the 126w but its hard to pull the trigger on a 500$ light when i see so many different opinions on them. im thinkin i just want something simple that can gimme an ounce per month for personal smoke, think the 63w is capable?
