How much did the bathfans cost you? So on the bottom are just vents. Metal? Or Wooden? (the closet) I am in Plastic with the rubbermaid. For the most part it has been ok for me, I was thinking of a 50 cfm, for 15 bucks and slaming that on the rear of my unit. Then I would still need one big vent or 2-3 little ones. Right??? What about the 50. I think my space is a lot larger, but far from nicer. I am just tanks and a light in a huge rubbermaid shed. The tall oversized closet one. ha ha, For now I keep the door cracked and it brings my temp and humidity to perfect. Of course if I seal it first things first, my humidity shoots up. So I need the vents to be able to close the door. Well talk to you soon, Lata.
