I used hides with a couple of them at the start but since I use newspaper for a substrate they can go under that and have it touch them on all sides ( which makes them feel secure ) without there being any need to adjust anything as they grow.

The main idea is really that the whole rub becomes their "hide" so they can select the temp they want to be without having to feel exposed at any point.

I've never tried a rack with lizards though so can't speak to that.
