This substrate has been designed specifically for Leopard Geckos, as well as other dry region species. Featuring a sand and soil mix that is more natural to reptiles, rather than a pure sand which is often provided for desert species.
This provides a realistic looking and feeling substrate that allows for plant growth, by holding humidity in the lower levels, exactly as natural soil and earth would do. This means that the deeper the reptile burrows, the more humid the environment becomes, exactly as they would expect. This means that pets such as Leopard Geckos can have natural hides and burrows which will help with their shedding, rather than providing unnatural looking "wet boxes".
