Definitely no yield for CFL, but they are good for Veg. It also depends on your style of growing. I suppose that's what it all boils down to is preference of style... Me? I'm a 30 plant SCRoGin' LED guy waiting for the money. The OP might be a HID guy who wants 5 5ft tall monsters at a time to drop mondo-yields. If that's the case, OP, get yourself a much bigger closet, a 400w MH, a 1000w HPS, a 6" inline fan with a scrubber, about $200 in beans,soil and amendments, and a whole lot of patience.
