Yep, you certainly can, though you need to take a little extra care to make sure the medium doesn’t stay soupy for too long. But about once every two weeks I’ll soak the terrarium floor so the water level is just about to reach the surface, but never enough to make any of the bark and stuff float, and this keeps the humidity quite high for a while. I do try and spray once a day, but with this setup they stay pretty happy even if I forget to spray for a few days.

If you’re curious about the medium, it’s nothing special. I just do some handfuls so that i get a mostly equal amount of orchid bark, sphagnum, and whatever those clay/lava ball rocks are. I think as long as there’s not too much of anything that allows fungus or molds or other microbial life to thrive, they do well and start sending out roots and latching on to the stuff.
