I know it's been asked multiple times, but I haven't found what I am looking for.

I've had my snake for close to a month now, he is 8 and I bought him and his enclosure from his previous owner.

This being said, he's been in the same tank for 5 or more years now, and there's been no issues.

Except I can't for the life of me get the temps and humidity up.

He had a very small water bowl that came with the tank on the cold side and I went out and purchased a large soak bowl which is on the hot side as well as I got an additional small bowl on the cold side. He has a heat lamp and UTH on the hot side, but the temperature wont go higher than 85°.

The humidity is way too low, like I said i added a huge water bowl, the tank has a cage like secured top which I have a towel over, I run a humidifier right next to the tank, I mist the tank daily, and now I am trying the wet towel trick, which slightly worked.

I want to know what works for others. What kind of substrate do you use? Do you mist? Do you use moss and what kind? Basically anything that will help me will be appreciated
