Hi,

Most people in tanks are using screen tops which cause part of this problem.

Heat lamps also affect humidity so the most recomended method is to cover the outside of the mesh top with tinfoil and tape it down (make sure there is no tape inside the enclosure) then cut a hole for the heatlamp if they use one.

Also it might be worth insulating the back and two sides of the tank if you aren't already as this helps keep the temps a bit steadier.

Have a search about for tank setup threads for other ideas etc.
