HYDROTON^® aka Pot Pebbles

HYDROTON^® - The world's famous expanded clay
HYDROTON^® - Expanded Clay Pellets
HYDROTON^® - Clay pellets are a popular hydroponic medium around the world.

Derived from a renewable and plentiful source (clay), HYDROTON^® is considered an ecologically sustainable medium. The clay is formed into pellets and fired in rotary kilns at 1200°C. Thereby the clay expands like popcorn and becomes porous.

HYDROTON^® pellets are light in weight, do not compact and are completely reusable - they can be cleaned and sterilised after use. They are also inert, pH neutral and do not contain any nutrients. The pellets drain freely and do not hold any excessive water, which is why they provide good oxygen levels around the root and why they are particularly suitable for flood and drain systems. They are also used extensively for rose growing.

HYDROTON^® is a substitute for normal plant-soil and is mainly used in hydroculture / hydroponic systems as well as for decoration.
