do you have a thermometer in there? I know you have that huge exhaust but still.. might be a good idea to check on the temps.

Also, what are you doing for intake? I didnt notice in your pictures. Your plants need fresh air, and your exhaust will work to its full potential if there isnt so much negative pressure.
