I would go HID. The initial cost of CFL hardware and the increased running costs make CFL unsuitable for most flowering applications imo. If you have temp issues it would be more effective to spend money on better induction and extraction for your HID lighting system (air cooled reflector hood etc...).

Or you could go LED.
