It'll work for now until the plant can support itself. I see you have no reflectors around your CFLs. You are loosing a ton of light. Make a ghetto reflector out of an old beer or soda can. It will disperse the light down, instead of it going in every direction.
You'll have 4 plants, the more CFLs the better, keep them as close as possible. I have 2 self ballasted 250 watt CFLs running with a 400 watt HID & I can get the CFLs about 1 inch from the plants.
