Clay Pebbles are traditional round-shaped pebbles of expanded clay. They have a coarse surface with lots of pores, giving them a huge surface area which allows them to hold lots of water. Because the clay pebbles are hard they do not compact down and they retain air-spaces between them providing lots of oxygen for roots.
