the best thing i can think of is a "cool tube" that you place around your HID bulb. I would think that that is ur best bet. good luck!
Juzt JR Reviewed by Juzt JR on . does glass stop heat at all? I need to make a stealthy grow box for the basement and im using a 400hp, so how can i ventilate this guy quietly to keep heat out. I know your gonna say small computer fan or whatever but if the top of the box is made of clear glass will that block any heat at all from getting in? i know tinted windows can keep heat out but is clear glass absolutely useless for keeping heat away or what? if so are there any other ways i can keep my grow box cool without alot of noise? thanks alot guys Rating: 5
