ideal is 2700k... most cfl's are 3000k, which is close enough... but, you'll need alot of them, like 8-10 per plant for optimal results... however, the 23w's are sold in four packs for 10$, so you should be able to suplement yourself... tub flouros don't realy help, because they're isolated to where they are hung, so you don't get side lighting or adequate top lighting.

check out my college courses in my sig, realy good guide to anything about growing
