definately

unless you can cram all 3 plants into a 2sq.ft. area lol

50w psf of HID... that number for fluoro is definately going to be higher but the exact amount is debateable / dependent on the type of fluors you use

i try to keep a minimum of 80 psf with fluors, curently just over 100.. not to say that less wont work, but more will be better
