Best substrate?

[Snake Judy]

I use a screened topsoil, sand, peat mix with leaf litter and some dried spag moss across the top for ground cover and love it!

Cool! Sounds like we're on the same trajectory. How's it for humidity? Do you use springtails or anything? My new enclosure is gonna have about 5" of substrate and a drainage layer. Also planning to try adding in a few (sturdy) plants and see how they fare.
