Expanded Clay Terrarium Substrate

Build the perfect foundation for a healthy, thriving terrarium with Zoo Med Hydro Balls.

By promoting proper drainage and air circulation beneath the substrate, Hydro Balls help reduce the risk of root rot and create a healthier environment for live plants, reptiles, amphibians, and invertebrates. They are ideal for use in bioactive setups, paludariums, vivariums, and planted terrariums.
