I have tried everything to keep the humidity up in Edgar's cage. I have a 20 gallon tank, It has indoor / outdoor carpet as substrate, it has reflective insulation on top of the screen with holes cut in it for my lamps I have tried turning the lamp off but the tank gets to about 70. With the lamp on it gets to be 84. Edgar always sleeps on the cold side The hot side is 90 degrees, I have an under tank heater.

I spray the tank daily along with wetting the sphagnum moss, I pour about 3/4 cup of water on the sphagnum moss to wet it. I have the water dish under the lamp. No matter what I have tried the humidity won't get above 40%. I have a digital thermometer and humidity monitor that is in the middle of the cage about 2 inches from the bottom. He had a shed last week and all but his neck came off beautifully. He scrapped it off about 2 days later. About 3 days after I feed him I give him a soak in his tub. And I spray him with humidity spray tropical mist He is eating well, his skin is smooth and his behavior is standard for BP's.

What else should I do?
