Hi there. I am halfway through building a Rubbermaid Box. I was planning on using CFLs, however I have been given a 400w HPS bulb socket ant ballast.

So Just how powerful of a fan should I be looking at purchasing, seeing as this bulb nearly melts the plastic without one? Or should I be looking at cool tubes?

Cheers for the Help
