Still having issues in my four foot boamaster. It a wood one. So far I have tryed eco earth, repti bark, put moss in it, and now useing paper towels. I'm useing a gradient heat pannel from pro products that's hooked up to a herp stat. Within a half hour of staying down my tank it goes from 65 humidity to 38. Thinking of investing in a mister if I can't find a way to instulate the inside to keep humidity in. Was also thinking of gluing acrylic on the inside to insulation. Please help. All ideas would be helpful. Never had a humidity issue like this.
