Clay balls for a terrarium
A terrarium needs a layer of inorganic materials to hold the bottom water reservoir keeping the terrarium moist. Simply placing a layer of dirt at the bottom will cause issues as water will collect there, causing mold & root rot. More on building a terrarium.

Should I add clay balls at the bottom of the pot?
NO! You may sometimes find the recommendation to add clay balls to the bottom of your pot for 'drainage', however, we strongly recommend against this.
If you add clay balls to your planter, instead of using a pot with drainage holes, you essentially create a water reservoir beneath your plant's soil.
This keeps the roots of your plant exposed to water continuously, which will quickly lead to root rot.
Instead, simply use a pot that has drainage holes to allow excess water to drain from the pot!
