Canopy Ventilation

[Lampshade]

+1 on the CPU fans, get a 12V adapter and get a 6" CPU fan. Works great, lots of air movement, low noise, and best of all, cheap. If you're venting outside try a used building material place for an old bathroom fan and get a wall mount dehumidistat. I've been looking at doing this because if i have my fishroom window closed for a few days i get condensation on all windows in my house, and having the window open on some of these cold nights is probably costing a lot.
