they are a new thing but the bad thing is you have water circulating around a light fixture(extreme fire hazard). you can aircool lights enough to touch the glass/tube with your skin and in the same time you can hookup odor control through a carbon filter
texas grass Reviewed by texas grass on . I'm in love I saw a water cooled light set up the other day running at 70 deg. w/ out a chiller. just a 50 gal. drum recurculating. I could touch the light with my bare hands. You can run these babies as cold as you want w/ chiller as long as you stay above your dew point. check it out. xxxx://bestcoastgrowers.com/garden/content/view/128/1/ Rating: 5
