Clay Balls

Clay balls, also known as expanded clay pellets or hydroton, are a popular growing medium used in hydroponics and aquaponics systems. These lightweight, porous balls are made by heating natural clay at high temperatures, causing it to expand and form small, round pebbles. Their porous structure allows for excellent aeration and water retention, making them ideal for supporting plant roots in soilless growing environments.

Clay balls are widely favored for their reusability, pH neutrality, and ability to provide stable support for plants while ensuring proper drainage. They are often used in systems like deep water culture, drip irrigation, and flood-and-drain setups, helping to create a healthy environment for plant growth with minimal maintenance.
