Changing your substrate would probably have the best results for you. I use cypress mulch for my bp. I also keep moss in the hides that can be misted or made damp during a shed. Placing the moss in the hide creates a micro climate in the hide so your humidity gauge will not show a high number but in the hide it will be. Using this trick my tank stays between 40 and 50 but because of the moss I have great sheds and a very healthy bp.

I Also made a cardboard cutout that I covered with foil to cover the screen lid. It has a fairly large opening for the lamps so ventilation is not a problem.

Eco-earth does hold moisture well but it can take forever to dry out. I Mixed it with reptibark for my gtp to help with humidity. Being that she is mostly in her branches I don't have to worry about her laying around in to damp of a substrate. Cypress is just easier to regulate. IMO. Maybe mixing cypress mulch with eco-earth would be a good solution. I have wanted to try this combo but haven't since the moss gives me all I need.
