What Kind of Substrate Do You Use In Your Enclosures? Hey, What types of substrate do you all use in your python enclosures? I currently have a 15' burm in a 7'lx3'dx2't enclosure on tile. I've been considering adding some kind of substrate because I can't always clean his enclosure immediately and the tile/grout is water sealed so the copious amounts of fluids he excretes form a puddle. I thought that perhaps the substrate would absorb some of the puddle. Also, any suggestions for substrate would be amazing!!! Thanks!
