"• Quantity 1. Plexiglas with cut to lid size with a central hole for the CHE. $40.

The mesh in the lid will allow too much heat and humidity to escape (the big problem with a glass vivarium). The plexiglas will cover the mesh except where you mount your CHE. We found a local plastics supplier (S&W Plastics) that cut us a piece to size including a square central hole.

Alternatively, you can use a piece of heavy clear vinvyl with a hole cut, which may be available from craft or fabric stores."


Does this not restrict air flow and ventilation too much if you cover the whole wire mesh lid besides a cut out for a heat lamp? During my snakes sheds its hard to get the humidy up to 80% in my tanks. Ive been placing a wet rag on the top of the mesh wire on tank lid.
