Substrates in natural terrariums serve many functions and are not only there for decorative purposes. They play a very important role in the determination of the terrarium's microclimate. The Exo Terra® Coconut Substrates are ideal to create natural planted terrarium set-ups for humidity-loving reptiles, amphibians and invertebrates from tropical environments. The hygroscopic properties of the Exo Terra® Coconut Substrates regulate the terrarium’s relative humidity in a natural way by absorbing and slowly releasing moisture. Adequate relative humidity levels aid in shedding and help prevent respiratory infections.

This ecological substrate is the safest on the market for use with reptiles, frogs, salamanders and burrowing & digging animals. Because of the desalination process, these substrates are even safe to be used as a nutritional planting soil for live plants in a natural planted terrarium setup. The unique coir pith used for the Coconut Substrates consists of a mixture of short fibers and coco-peat grain sizes ranging from coarse granules to fine clumps resulting in improved soil drainage and aeration. This improved aeration promotes a flourishing population of beneficial, waste-reducing, nitrifying bacteria, and prevents root rot, making the Exo Terra® Coconut Substrates the safest choice for naturally planted terrarium setup.
