Anyone have a recommendation (or maybe commentary) for a small GH fan? I have a 12" Schaefer up high, but I need something to go beneath the benches. I can shield it pretty well with some plexiglass or something, so it won't have water running on it. But it needs to be able to withstand near-constant 100% RH. In other words, a sealed motor would be awesome. I'm thinking maybe a 6-10" fan would be ideal.
