Do the cords get hot? I am just planning my grow room and I didnt think to ask if the cords get hot. I used ducting tape (metal tape) to tape the cords to my a wall. Will this be a problem? I dont think it will because Im sure they make the cords insulated just wanted to ask someone who has had an indoor grow and could give me some advice. ALSO I have my ballast inside my grow room (only way possible) I put a vent right under them, and raised them off the ground, my ventilation is 60cfm and its a 60 cubic foot room with an extra fan. Will this keep the temps down (400 watt hm) any idea?
