I could be wrong, but you're probably going to get too much blowout if you don't close the back off. Then get a black mesh tarp to the cover the top so the air can escape.
Absolutely, I have a mesh tarp that I was going to cover 1/2 of the top and the back with. Perhaps a wood back would be better, I'm going to see how it works tomorrow and make some adjustments if need be.
