This 36 qt bag is the bulk format of Terra Firma, The Bio Dude's handcrafted bioactive substrate for terrestrial burrowers — snakes, monitors, tortoises, and other digging species — at approximately six of the standard 6 qt bags in one. It's the practical size for a 4'x2' ball python or skink enclosure with real burrowing depth.
