Okay, So I have a 430cfm exhaust fan in a 42 cubic foot room and using a 400 watt light. I also have an oscillating fan blowing. The length of the ducting for my exhaust is about 15 feet if that matters. My problem is that the temps are reaching up to 97 degrees! I don't know what the problem is. Also the lights are on 24/7 if that is a problem.
