You can make anything into a humid hide by hot glueing a sponge to the ceiling. Hollowed out logs, terra cotta, name it! My glue gun has got to be in the running as one of the best $10 I ever spent!
My humid hide isn't natural (plastic flower pot with holes in the bottom-I can see the sponge through the holes-so I remoisten by squirting through the holes onto sponge), but it would be NO problem for someone to take just about anything and make it work......................
Your question sounds like an invitation to tinker............off to get the glue gun out again!
Anybody interested in getting out their camaras and having a natural-looking-humid-hide show off?
Little creativity be good for da soul :wink:
