Well I came to the conclusion, after reading a lot of threads on heat issues, that I'm not going to able to do a MH/HPS system like I was hoping. I'd have to be drilling into the attic and through my closet door and at this point, that's just not going to happen. So I decided to go with floros. Ordered this......www.plantlightinghydroponics.com/te...ens-4ft-t5-fluorescent-grow-light-p-1924.html Got it with 8 6500k bulbs and added 8 3000k bulbs for blooming. I can't wait to get started. I hope it's not to much of a let-down, after salivating over a digital 600W MH/HPS dual system. Will probably be posting for advice and help. Wish me luck.
Nice light. It looks to be more expensive than a 400 watt hps but, at least they will stay cool. Good luck.
