I put it inside because I felt like the adhesive side facing down would be a bad idea just in case there was condensation buildup and it dripped into the enclosure with traces of the adhesive glue. Maybe I'm overthinking it?
And the log that's on the left is the warm side, and the other attached to the wall of the terrarium is on the cool side, and she can get under it or inside of it as a second hide. She moves between them as she feels the need to.
Thank you for the feedback
