Review on Lightweight HydroBalls Expanded Clay Terrarium Substrate by Zoo Med, 2.5 lbs by Alexis Jordan

I recommend placing these HydroBalls in any habitat that requires higher humidity such as a patio. B. our tree frog terrarium. Easy to install and what a treat it is to simply fill the bottom of your waterproof habitat with water rather than constantly misting it daily to keep it moist. You must purchase a screen to cover these clay balls before installing the EcoTerra substrate. They are quite a helper in caring for a pet.
