Greetings,
Just a quick question. I'm going to build a small grow cab with a foot print of about 30x33 inches. I intend to put a 430 Watt HPS in there and grow a 3-4 plant scrog. Now I want to get my light down to give my screen the ideal amount of light. I was told for a 400 Watt that's about 18-24 inches. Now that's distance between light and screen the buds will be growing up into that space and I worry about the heat. I looked into a cooled hood but can't fit one in there comfortably. So I saw something else that might serve. I want to now put a plane of glass at about the 24 inch height (above screen) and lower the light right down almost on it. Then have a fan mounted slightly above that to blow on the light and glass. The fan I want to use is a 120mm PC fan on steroids. The thing is rated at 200 CFM.
Think that'll keep the temps reasonable? The rest of the cab will be having its air exchanged by a 95 CFM fan with a carbon filter..
Thanks!
