Clay pebbles (also known as hydroton or LECA—Lightweight Expanded Clay Aggregate) are small, round balls made from heated clay. They're commonly used in hydroponic systems, aquaponics, and as a growing medium for plants. These pebbles have a porous structure that helps retain water and nutrients, while also providing good aeration for plant roots.
