Playmound and obzen - Thanks guys. Stick around, it should be good.
LymphNode - I hope you can pull more with your 2 150s then I can with my 70w. My first round with this box I did without the tube. I couldn't get the plants as close to it and my goal is to go to a bigger light soon. I might have to try it out tonight and see what happens with my 100w cmh. Last time I stuck it in there temps went up to 90 degrees before I pulled it out. My ambient temps are much cooler now so we will see.
