The clay substrate works well as a base layer under coconut fiber. It holds water effectively and keeps humidity steady. My tropical plants have grown stronger since using it in the terrarium.

I used it in a waterfall setup and it helped filter the water. The moisture retention is good, though it needs occasional watering to stay moist.
