Hydro Clay Pebbles are an environmentally friendly grow medium that can be reused again. These clay pebbles have been fired in super-heated kilns causing them to expand and become extremely porous. These tiny holes and crevices inside each pebble hold and transmit extremely high amounts of air and water to the roots of your plant, helping them grow bigger and faster, and making them perfect for hydroponic systems.
