Just a suggestion but to help with humidity you can cover almost the whole top of the screen top with aluminum foil. This will help keep the humidity from escaping, it may also help keep some of the heat in. I use a glass tank too. It may also help to cover three sides of the tank with paper to black it out and or insulation to help with the heat. Since I took the picture below I also have added insulation board around three sides and covered a little more of the top with foil. This has helped greatly with heat and humidity. Very important to get all heat sources on a thermostat and a heat gun (you can buy one for like 10 bucks on Amazon) makes it easy to spot check your temps daily so you know they are accurate.
