Can you cut a hole in the top of it? If so, go get a 4,5 or 6" axial fan and mount it to the top so the airflow is exhausted from the space....you may or may not want to install some duct work in the same size as the fan to move the warm exhaust air away from the grow space...it should be a simple two wire, possibly 3 wire connection....black to black, white to white, and green is the ground wire. If both wires on the fan are black, it doesn't matter which one goes to white or black, but green is ALWAYS ground!...hope this helps!

My axial fans are just two wire tho, and grounded thru the frame of the fan itself. You may have to make your own ground wire and attach it to the frame of the fan. And it should be grounded! That space should work well if you can control the heat issues, and get plenty of fresh air to it! Good Luck!
