yeah bro, your gonna need at least 8 42w compact flourescent bulbs,
get some y sockets and 4 of those painters lights with the aluminum reflectors.
you can get all that stuff pretty cheap at lowes or home depot.
you, want your lights to be as close to your plants as possible, put your hand directly above your plants and then lower the lights until you feel the heat on your hand, thats as far away from your plants you want to keep them, always check them, cause you have to adjust them as the plants grow
