The BioDudes handcrafted Terra Sahara Bioactive Substrate is made for reptiles such as bearded dragons, uromastyx, leopard geckos, and other desert-dwelling reptiles. This substrate is specifically designed for biomes that can get very dry and arid, but occasionally have minor humidity spikes. Terra Sahara, a one-of-a-kind bioactive substrate, is designed to hold the perfect amount of water while allowing for evaporation, preventing anaerobic bacteria growth, which is a common issue in desert terraria. Terra Sahara also retains all burrows and hides. I have found this substrate brings out many of the instinctual niches that many desert animals do in their daily life. Not only does it hold a burrow, it also holds a complete tunnel when the moisture content is held at 25%-40%. Terra Sahara provides excellent organic nutrition for your vivarium by creating necessary air pockets for root development and plant health. These air pockets are also necessary for the springtails and isopods to create a sustainable population in the vivarium. 

Note: Each 6 qt bag of Terra Sahara weighs an average of 8lbs.

There is no drainage layer needed for the Terra Sahara.
