Paper towel substrate.

Thanks for all the replies!! I will put a pic up as soon as I figure it out haha. My humidity issues are that its too low. I have the UTH on a dimmer but don't feel like it's warming up enough. I have a probe digital thermometer that I just placed on the warm side right above the bottom and the humidity reader is In the middle about an inch and a half above the bottom.
And the I was using a heat lamp but got the UTH yesterday. I have a light on a timer so that he has a schedule.

What's The Best way to post a pic?

I use wet paper towels in my humidity boxes, but for substrate I use brown butcher paper. Stays put, cleans up nice, and looks pretty good.

We use packing paper from U-haul. We don't wet the paper the snake normally does that to taste with the large water bowls. We also have a designated room for them and keep the humidity in that room around 60% with a humidifier hooked up to a whole house Humidistat. We use ARS racks and vision racks.
