Not to be a bitch, but why the fuck would you use CFL's if you have a license to grow... Use at least a 400w HPS. But to answer your question, depending on how many plants you want to grow, you should probably get at least 2 23w CFL lights per plant, or make a large strip with at least 5 on each side. Or you could get the larger 42w CFL's. All sold at your local home depot :)

yeah bro i agree, if you have liscense then go hps or mh but if cfl is a must, then get as many biggest ones as you can get, and make sure to get ones witha color temp of 5000k-6500k for veg and 3000k for flower
