hello I am currently growing under a CFL bulb for one plant but am wanting to but a grow kit that includes a 400W MH and a 400W HPS bulb. however I don't know whether or not to buy the kit that come wit the wing reflector or buy the one that comes with the cool hood. which is better? if I use the cool hood how do I set up the ventilation system. if I use the wing reflector how do I control the heat.
