I make my own "humid hides" by cutting a hole (doorway) into the top of a large plastic food container, one that's big enough to hold a fair amount of either soaked* sphagnum moss or soaked (& drained*) orchid bark PLUS the snake. Snakes LOVE these things for the privacy & super-humidity & you want them partly warmed by whatever heat source you're using (I use both UTH & overhead-); you'll need to re-humidify the contents periodically, of course. I prefer to use rectangular containers but others work too, the main thing is having enough room & depth.
