everyones already giving good advice.
heat on both sides isnt taboo if the room the enclosure is in is too cold.
id switch to cypress mulch mixed with moss.
aspen works for others but didnt work for me.
my bp didnt like hides i offered..i had tupperware bowls and rock caves.terra cotta pots seemed to be the trick.oh and a coconut hide worked.
my bp would only eat in her enclosure and if i wasnt in the room or covered her tank with a sheet.
oh and covering three sides helps.i got a background on the back and fake plants on the sides obscuring the view.
