Wow That is alot of questions ok lets see the temp for hot is ok i can make it between 88-93 the humidity is usually in 30's tho without the misting I am using a basking lamp above heated side and pad below. I have a 20L tank with 100% fir bark i dunno how much I really just filled the bottom of the tank all around bout an inch high. I took the other snake back to petco and washed everything.
