if u want to spend money go for some of the new t5 s from htg or somethin, but if ur lookin for an economy grow get some 4 foot shop lights for home depot. CFLs are good but they more used for spot lighting, id say go fo tubes
I have been reading alot on CFL. They seem to be great. i went out today to get some spent about $40 and got about 8 blubs. they cost ALOT less to run then a hps or MH. PUT U WILL NEED ALOT OF THEM TO FLOWER.
