BT, that tent is so nice and ROOMY! I bet there's an echo in there somewhere. Have you ever tried a vertical bulb setup?
I've been wondering about doin a vert set-up with both my 150w hps but I'm not a electrician so I haven't really fucked around with taking apart the lamp. But if I upload a pic or 2 of the lamps is it possible to get pointed in the right direction. Thanks fellas!
