I ended up finding 10 packs of regular black garbage bags at my local dollar store that worked perfectly. $1.14, and some careful work later my box was completely covered in duct tape and garbage bags. The only light that leaves the box is a tiny bit at the zippers and at the hole where the screen is cut out for the fan. I will figure out a way to change that when it comes time to switch to 12/12 outside of that box. For now nothing is going on outside that little box. Thanks for the props on the reflector. I wasn't really sure about the design but I like the final product. It does an alright job and still allowd for individual height adjustment of the lamps. I wish I could find more wattage for the box but my local stores don't carry anything stronger than a 26W in 6500K. There were some 42W 2700K and I think I may buy one or 2 of those. I figure more wattage and more lumens in a CFL grow is never a bad thing.
