You can try U Grow on the south side. 18' and 24' reflectors for about 25 bucks. They are white, not polished aluminium. From what I understand, the white will work just fine, and much cheaper. When you mount it, you should put a couple of 1"*1" strips of wood onto the canopy and mount the reflector to that. This will allow some air movement above the reflector.
