If you want to stick with CFLs they do work. Many people on this site have done their entire grow with CFLs. The key is to remember is more is almost always better. Start off with 3 in the blue spectrum(one bulb over the plant & one on each side). When you flower double the amount of lights if possible & make sure they are mostly in the red spectrum w/ a blue or two. Surround the plant as best you can with these lights so that every part gets equal light as CFL light penetration is not the best.
