CFL's are compact fluorescents. They sell them at any hardware store, just ask.

The problem is, the amount of light you're giving them is not sufficient. Yes, you see growth but it's not the growth you want, necessarily, since they're stretching to get closer to a light source. You're definitely going to want to get some cfl's, get them one or two inches from the plant, and get it on a correct lighting schedule. You may be able to save yourself from male, but there's already some stress done. Wait and see I guess.
