The fan on the AC filter is a 150CFM, but I'll have to turn it down abit for noise but it should vent evety min or so. The cabinet without the fan running is 74 F and that went up to 83 with the fan and HPS running.If the light is too strong I'll have to pick up a few cfls,but how big do they have to be before using the HPS?
BCsquatter Reviewed by BCsquatter on . 1st grow This is my first grow, using a old kitchen cabinet (24dx30wx64h) with a ac filter and fan installed in the top. I started them with a 70w incandecent grow bulb and am wondering if I can start using the 600w HPS now they are popping up (keep it 30" away from the seedlings?) or is that too strong for seedlings? Thanks Rating: 5
