Being a beginner you might want to work a little longer with what you have; if for no other reason than to get the basics dialed in.

CFL setups are great for learning the basics. You're going to experience several more challenges utilizing HPS or MH particularly as mentioned- with HEAT. Heat can impact your productivity in a negative way in close quarter grow setups. You're going to have to find a way to get the temps down by isolation of your ballasts outside the grow room/closet and adding a vent fan if nothing else. It ain't rocket science but there can be a learning curve for the newbie. Just wait until you get a whitefly infestation too! Lol.

Good luck and remember to have fun with it whatever you end up deciding on! For me it turned out to be a new hobby in which to dump money, heheh. Unless of course you consider the free high grade meds I've grown!
