yeah man I hear you. I have a smaller box myself and my temps are through the roof! Its really driving me crazy because I have two girls in there now and I've had to reduce the lighting to keep the temp down... I'm talking like 1 to 2 23w bulbs with the door open.. something is definitely wrong. But hey your setup looks good. I know what you mean with the space issue. My last pc grow I took the side off and just mounted a light right on the side, but those were the good old days when I didn't have to be TOO stealthy. Now I'm killing myself trying to transform a normal looking object into a grow box. I have the perfect setup just cant tweak it... Idk anyways Good Luck! I'll be checking back to see how she's doing. Peace
