The Exo Terra Stone Desert mimics the natural soil found in arid regions, like deserts or savannahs. Most desert soils are not purley sand-based but rather a combination of sand, decomposed granite and clay resulting in an interesting and sometimes colourful rock formations. Exo Terra's Stone Desert allows you to create your own desert or savannah landscape, including cool-humid burrows as well as warmer elevated basking areas. Lightly moisten the stone desert substrate to shape naturalistic hills, burrows and basking platforms for your animals. Once dry, the stone desert will retain its shape, while still allowing your reptiles to further execute their natural digging and burrowing behaviour.
