Bioactive setup for Thayer's kingsnake

[KarenL]

I would like to set up a planted bioactive tank for my Thayer's kingsnake Ra but I'm not sure if that will work for him as he is a desert species. I do keep a leopard gecko in bioactive with humidity in the 50% range which seems to work well and has really improved his shedding problems so I don't see why it shouldn't work with appropriate low water plants, but I wanted to check because I am worried the increased humidity will give him respiratory problems. Does anyone here have experience of planted/bioactive set ups with species that require lower humidity?
