Thanks for the reply. I am currently using CFL's and a 50 CFM exhaust fan to move the stale/hot air out (it is sort of overkill in the CFM dpt. and 4 sones loud) but anyways, I still need to add an intake fan or two. I also have 2 fans circulating air inside a 6" and a 4". If you have a long dresser about 3.5' high, I gutted the drawers and made a solid piece to fill the space light tight. there is a divider between the two sides also light tight and allows me to have two chambers on different timers. so now you can sorta get an idea of what I'm working with. pics to come soon.
