Terra Fauna Bioactive Substrate, 18 Quart

The Bio Dude's handcrafted bioactive substrate for rainforest-dwelling reptiles such as Day Geckos, Crested Geckos, and other neo-tropical herps. This substrate is specifically designed for biomes that can get quite warm, but have humidity spikes throughout the day. Designed to retain water and drain efficiently into the HydroGrow, Terra Fauna 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. 

It is highly recommended to use the HydroGrow Drainage Layer in conjunction with the Terra Fauna.
