I have a 10g glass tank (the Exo-Terra kind). I have a UTH and a 25 watt light on the top of the tank. I covered the open screen with a towel. I have insulated 3 sides of the tank with black foam core board.
I am getting between 45-50% humidity. Near the UTH I am getting low 80's, and by the light I am getting high 80's.

I am not sure what the surface temp is for the UTH, but I am sure it is around 100 because it is very warm to the touch.

Are these temps alright? Or should I be doing something differently?
