Exo Terra Sub Stratum Bioactive Volcanic Substrate 4kg

The Exo Terra Sub Stratum is collected from the mineral-rich foothills of the Aso Volcano in Japan. The natural volcanic soil, formed from andesitic and rhyolitic tephra, is very nutrient-rich, and ideal for lush plant growth in bioactive planted terrariums.  The porous surface allows for excellent drainage and aeration, supporting strong root growth. The Sub Stratum’s friable, low-density structure promotes a flourishing population of beneficial, nitrifying bacteria, creating a self-sustaining, living terrarium ecosystem. The active beneficial bacteria of the soil will decompose biological waste, keeping the terrarium clean and healthy.
