10x10 eh? That is quite a large grow area haha.. with CFL's the main problem is lumens disipate very quickly so they would need to be about 2 to 3 inches away from the plants at all times to get any decent yield. if you could build a 4x4x4 cube (wood, cardboard, etc.) and paint it flat white or cover it in emergency blanket you would concentrate the lights greatly and get a better yield opposed to just popping them in a 10x10 room...
