i just got one, im using cfls aswell. one 125w with the reflector that I am going to have hanging above the plants. (Having a bit of a nightmare with the light hangers atm)
Then I have a couple of 40w around the sides and rotate them twice daily.
i use a 600hps in a 3x3x6 for one of the flowering rooms. CFL's arnt going to cut it.
