like granny has already said, yes, you can grow plenty of quality bud under
fluorescent lights. in fact, if you're on a budget, fluorescents are a good way
to get started growing as you can begin with nothing more than a couple CFL's.

heres a couple pics of a 4 bulb fixture i picked up for under $5.00 with y splitters
to up capacity to 8 bulbs and an early shot of that fixture in action.
