I am still planing my build but I plan on framing up a 4x4x7 box with 2x3's and plywood or plastic. What would be best for my space I want the 600watt hps but how hard will it be to keep cool in this set up. I am willing to go air cooled but people still say heat can be a problem. The grow box will be inside the house were it is kept at 75F and this will be my intake air. Also will the 600watt yield that much more than the 400watt.
