Another forum member asked me earlier to put up pictures of my planted California Kingsnake enclosure. Sorry for taking so long to get them up.
I planted this one much the same as all of my enclosures. Started with about an inch of small gravel, covered it with fibreglass screen, then added about 4-5 inches of soil. For soil I mixed topsoil with coconut coir, ground sphagnum moss, and some fine charcoal. Im contemplating getting some Salaginella for more ground cover, but we will see how it goes. Let me know what you think.
