First time blogging ever. Good place to start. I have an 8'Lx6'Wx7'H room, with 2 1,000 watt lights and a 750cfm charcoal fan, the fan is hooked up to the ceiling, and 2 circulating fans inside. I also have a 450cfm fan on the outside of the room,inside the vent. Not to mention, 4 labyrinth air vents. The walls and floor are covered with permaflect. I can't get the temp below 90. Any help would be greatly appreciated.
