you'll need at least twice that many. i had 2 double 48" floro fixtures with 4 k+b bulbs, and 16 23w cfl's for 8 plants initially. traded the floro's for hps, will lose the cfl's when i have another hps running. downt to five plants.

obviously you are vegging. how old are your babies and how much room do you have to flower?

love, kp
