TheGreenFog if its getting that warm in your cab maybe you should freeze 2-liter soda jugs with water (turn your freezer on its coldest setting) and place them in the bottom of ur cab during lights on period do this with like six 2-liter jugs and u should have a constand supply of frozen jugs , change them once a day should keep your cab a few degrees cooler. Just a thought. Nice cfl grow.
