Hi Chomsky...

If the air in your room is the temperature that you want to keep inside YOUR BOX... Then you should not be having a problem... Especially if your exhaust fan is replacing the air in your box every 2-4 minutes...


I must assume that your room temerature is HOT.... Therefore it will be impossible to lower the tmeperature in your grow box...

If your room temperature is not hot, you need to get a more powerful exhaust fan and make sure you are blowing the warm air far from your grow.. preferably OUTDOORS or into an attic.
