My first grow I used two 50w HPS' from clone to harvest. I actually like HPS because the light is pretty intense and is way cooler than a bunch of CFLs. CFLs individually don't create heat. But I tried using some with my two 50w HPS' and it got really hot. They seem to create a lot of heat when you have quite a few.

For beginner growing, those 50-70w HPS' are awesome, and they are small. Low budget is needed for a stealth grow.

About the reflective material, you could paint the inside or buy some mylar. I wouldn't use that foil tape that much or foil itself. It's not that reflective and could great hot spots which hinder growth because the Stomata on the undersides of the leaf aren't getting fresh air (if you don't know what I'm taking about pm me about the grand importance of air circulation).

Because of that, I think you should also get two 120mm computer fans that are at least 100+ cfm. That'll do your ventilation trick.
