Lol, i made 2 exausts. One is a computer fan blower into a drain pipe for a gutter under crack under doors, other is a house fan set inside of a box where he box has a hole in it that blows through carbon.
I copied someones idea for $3 carbon filter and just did my own twists to it. But i hope this stuff works :S its not the same type as his, couldnt find it.
Also I got rid of the halo's. I now have 2x long 40watt flouro's 150watt flood and 4 CFLs.
