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® Tropical 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® Tropical 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.

The Exo Terra® Tropical Substrates are extensively tumbled to smoothen the particles and remove excessive dust, than heat-treated to reduce bacterial contamination. This ecological substrate is the safest on the market for use with reptiles, frogs, salamanders and burrowing & digging animals. The unique size and shape of the bark particles allow frequent irrigation of your plants while still providing good aeration for healthy root growth. This improved aeration promotes a flourishing population of beneficial, nitrifying bacteria, and prevents root rot, making the Exo Terra® Tropical Substrates the safest choice for naturally planted terrarium setup. Exo Terra® Tropical Substrates are absolutely non-toxic, free of chemicals & pesticides and can be safely composted in your garden.
