Hydroton clay pebbles (aka expanded clay pebbles) are clay balls that have been expanded to form pebbles. Some people also call it LECA (lightweight expanded clay aggregate), the scientific name for clay pebbles, and it stands for Light Expanded Clay Aggregate. So basically LECA and clay pebbles are the same thing.

Clay is formed into small clay pellets and then kiln-fired at temperatures up to 1200°C. This process causes the clay to expand and create tiny air pockets throughout the clay ball.

These properties make hydroton a versatile growing media and ideal for use as a growing medium or hydroponic substrate. They are also very popular for aquaponics, as they provide a home for beneficial bacteria and can be used to filter water.

Hydroton clay pebbles are available in a variety of sizes, but the most common size is about the same as a grape.
