Plenty of people use cfl's for grows, you just need to buy a lot of them and constantly adjust them. People say they get dense nugs with cfl's, they look nice, but hid's penetrate much deeper and make much denser buds. Nothing against cfl's, I would just rather have 1 light to adjust and 1 cord to run, i dont like clutter in my tent. I dont know where your located but if you want to run hid, search for a 400 watt dimmable digital growlight, it will run bot mh/hps bulbs and you can run it at 200, 300, & 400 watts. I run 600 lumateks with Digilux bulbs and love them. Keep the air moving and watch your temps and youll be good.
