You have what looks like a very serious electrical hazard there.

I can't tell you to stop what you're doing, but I'd seriously recommend assessing and changing it.

Speaking of co2, you're WAY ahead of yourself with what you're showing. Start here: http://growweedeasy.com/the-basics-of-growing-marijuana

Getting into a 400w HPS with CFLs, I'd always recommend a 440CFM typically dimmed down, depending on space.
