Hydroton expanded clay is a popular growing medium around the world. Hydroton expanded clay is light weight, does not compact, is dustfree and is completely reusable – it can be cleaned and sterilized after use. It is also inert, pH neutral and contains no nutrients. Because the pellets drains freely and don’t hold excessive water, they provide good oxygen levels around the root zone and are particularly suitable for flood and drain systems and hydroculture systems.
