out of curiosity how many lumens are you folks running in your veg and flower rooms. my veg cab is 2feetx1.5 feet x 2 feet tall. 10 cfls 6500k total=16500 lumens. that's 5500 lumens per square foot of floor space. (vigorous growth, zero stretch)
in flower im 2.5 feet x 3.5 feet x 5 feet tall. i run a 400 hps in here with cfl sidelighting total lumens=66000. that's about 7500 lumens per square foot of floor space.
