How to keep a stealth grow colder

[blitzkriegen]

I currently have a stleath grow in a cabinet that is 11.5 cubic feet. There are 6 26 watt cfls, and it is upstairs so it is about 85 degrees in the day and around 70 at night. I have a 50cfm exhaust fan, and it helps a little, but i still need to get the average temperature down about 5 to 10 degrees. Does anyone know the best way to keep the temperature down? Thanks.

Does the entire room get 85 degrees in the day? or just the cabinet. Increase your airflow if your room is staying below 85. If the room itself is getting 85 degrees there is no way to drop the temp below that, unless you air condition the room.

I second that. You need to AC your room. Cheap AC can be purchased for $100. Around 5000btu, uses about 4.8amps, fits in your window. You cant bring the cab temp lower than the room its in unless you AC the cab.
