The pantyhose might not rot, but won't you still have a bacterial growth problem from fecal matter dropped by the cham getting into the wet peat moss/sand mixture?A false bottom raised up about an inch with a drain on the floor, egg crates (plastic ones) wrapped in panty hose and then a couple inches of substrate. A veiled cage would look pretty cool with play sand and a little peat moss mixed together. The panty hose would keep the substrate from running off and is not organic so it would not rot. Of course with heavy mistings the water might stand for a minute or two. Maybe something I will look into in the future but then again I am pretty lazy so maybe not.
