if you really want to get crazy look into this Hydrogen 6 Inch Ice Box Water Cooled Heat Exchanger - Plantlighting Hydroponics

I have 8- 1000w hps lights connected with 2- 700 cfm fans and one of these every other light tubed back to 2 - 100 gallon reservoirs with a 1 hp chiller. I also run the hydrogen co2 water cooled burner in the same fashion. My room never gets above 85 degrees with everything running at max and no supplemental ac. These things work very well
Jord0713 Reviewed by Jord0713 on . Air-cooled hood...can you pull too much air through? I just picked up an enclosed reflector with 6" air-cooling flanges. I just ordered a 6" inline fan that is rated to 200 CFM, but it looks like it only runs at 160 CFM. I don't think that'll be enough for my 1000W HPS. My other option was a 424 CFM fan!! That air would be fuckin roaring through the hood! If my nerd calcs are right (Q=VA), then the air would theoretically be coming through the hood at 36 ft/s (25mph). That's a pretty heavy gale. Could that be harmful to the electronics Rating: 5
