I couldn't believe there were 17 posts on this subject before anyone mentioned *per sq ft! I'm jelous of both you guys (tric and bob) killer lumens! I'm only at 3,521 lumens/sqft and 24.8 watts/sqft (right now). That's with one 600 hps complimented by T5's and T8's. Still waiting for my first harvest. The guide I read mentions the following as ideal, 45,000 lumens for a 3'x3' area, and 20-50 watts per sq ft.
I'm wondering Corey and trevor, how do you figure grams/watt with a perpetual gro? (gr/plant)/(watts/# of plants)
