Expanded or expandable clay aggregate is a commonly used hydroponic grow medium. It is a lightweight aggregate that is heated in a kiln oven to a temperature of 2,910 degrees Frenheit (1,200 degrees Celsius). Once the aggregate is heated, it releases gases, which create small bubbles that make a honeycomblike structure inside of the aggregate.
