The hot air has to go somewhere. It must leave the growbox AND it must leave the closet. Cheap is not in the growers dictionary. Man up and spend the money.
Gotta exchange the air, you can't get around this. You need an exhaust fan of some sort. And BTW, tinfoil is useless as a reflective material.
You can't add cold to something warm, to cool it off. Instead, you must remove the heat by transferring it somewhere else. The most efficient way of doing this is to use a ventillation fan. Make vents (holes) near the bottom of your grow cab, and place an exhaust fan near the top of your cab. This will blow the warm air out the top of the box while drawing in cool air from the bottom. This will only work if the ambient temperature in the room is cooler than the temps in the box.
