I’m using a glass tank and after some tweaking and modifications my temperatures and humidity are perfect and stay that way with very little interference. I have a 20 tank. Cold side covered by plexiglass on top Wich helps to keep temps and humidity stable, heat lamp in the middle to keep ambienta up, thermostat controlled UTH to keep hot spot at 90. I bought a 20$ humidifier at Rite Aid (it sprays for about 8 hours on one fill) and set it on top of plexiglass. It perfectly keeps the humidity very steady and the snek seems to quite enjoy it. I have three hides. One in the middle is medium temperature (neither hot nor cold) and has damp sphangum moss in it. Sally loves chilling in there during day time.
With this set up my BP that came to me underweight, dehydrated and with a stuck shed has been eating like a champ shedding beautifully and looking amazing.

* I live in Cali so humidity is a challenge to keep up without the humidifier. Temps in my apartment are climate controlled and usually between 75-77 so the tank has to be warmer than that.
