I would ditch the lamp and switch to a UTH that is controlled either by a thermostat or at least a dimmer. BPs don't bask so belly heat is better.
You don't need to use moss in a humid hide. I used pieces of cloth that were damp. Another think you can do is cover the screen top with a towel or plastic wrap.
The spray paint should be fine as long as you used non-toxic paint.
I've heard some people bake sticks before they put them in. I've never done this but I'm sure someone else can chime in and tell you what to do. BPs are going to hide most of the time anyways so you really don't need it.
Good luck with your new snake!![]()
