to hot???

hey im new to th site and im doin a closet grow but one wall of my grow room is facing the road just looking for some ways to block the boys in blue from noticing the heat in the room and tip will b greatly appreciated thanks

hey you can get rolls of reflectix from home depot. i have the whole room covered in this. but that stuff reflects a lot of heat back, so what you cant see in the pic is from the floor up 5 feet is a layer of panda film on top of the reflectix witch is a little cooler. but my ceiling is still covered.
