I would try and get the most powerful CFLs you can get. Space is always going to be an issue, so you really wouldnt want to somehow make room for 10 lights.

Go to lowes and find a 30w or 40w. I heard the daylight cfls work better. Get 4 of them, one for each plant will be fine until flowering, where you can always upgrade when that comes, but I dont even know if you would need to, also considering you might get a male or two and reduce your light requirments right off the bat.
