I use pebble stones, and lots of fake plants from Hobby Lobby or Michael's like fake grass (most of my snakes and lizard appear to enjoy it), ferns or anything big fluffy leafy type that provides coverage as well as a nice jungle look to it. I also add corkwood in there and I have a humid hide purchased from Amazon for about $15 or $19, I think it is called a snake cave or something. Looks cool and gecko uses it.
