Thanks for the replys guys. How much yeild per plant can I expect in from nine plant harvest running 2 1000 watt Hps/ MH lights? Guestimation?

I think cooling wont be a problem right now cuz winter is coming (im in Colorado). I will regulate with fresh air from outside.

I think I will be able to just cut a hole in the wall of my grow room and place a good fan and filter blowing outside. I will draw in cold fresh air from the floor, I have a large crawl space under my house/grow room. The great part of this is it LEGAL.

Thanks
