Thanks Lynn. Thats what I was wondering. I have been having issues keeping the humidity up even though I have them in the hottest room in the house and away from drafts.

I do not currently have the tank completely enclosed. It is one of the 10gal reptile tanks that have the mesh lid that slides on a track. I have thought about getting a piece of plexiglass cut to place on top of the mesh , but wondered if it would filter out the uv from the bulb I have for the plants. Glass is not a really good option for me since my darn cats wont stay off the tanks. (I currently have light diffuser cut and zip stripped together like a canopy top to keep the cats from falling through the mesh.

I will try to get a pic in the next few minutes to post.
