Hey everyone!
I'm looking forward to some really great suggestions!
My young Colombian Red Tail Boa is in a coconut fiber substrate about an inch deep, with a rock to hide under/in and a large corner water dish she can drink and soak in with plenty of room to spare. there is also a driftwood branch, and a fake branch with fake leaves on them both as well as a climbing branch.

Ideally I would LOVE to set up a more natural environment, basically a biological one with live plants. I'm also have a rough time with her humidity. I'm always misting her tank but it never seems to be enough and sometimes a mold-like substance can be found growing.

Please help!
