Hydroton


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. This causes the clay to expand, like popcorn, and become 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.

In drip irrigation systems the pellets can be mixed with a medium with better capillary action so the feed is dissipated broadly through to prevent salt build-up. Hydroton is a substitute for normal plant-soil and is mainly used in hydroculture / hydroponic systems as well as for decoration.

Hydroton is available at most hydroponic supply stores and on the web. We at Patio-Gardener purchase direct from Everybody's Garden Center. Their prices and service are among the best around.
