Expanded Clay Balls: Quick Overview

Expanded clay balls are lightweight porous mineral pellets used in semi-hydro systems, drainage layers, terrariums, and self-watering setups. They absorb some water into their pores while leaving large air gaps between particles, which helps balance moisture and oxygen around roots far better than dense soil in certain setups. Because they are inert and reusable, they stay useful across multiple growing cycles if cleaned properly. Ideal for growers who want a clean mineral medium for propagation, reservoir-based pots, or drainage layers, and especially useful when building semi-hydro systems that rely on wicking and airflow rather than conventional substrate behavior.
