Applications

Horticulture & hydroponics

An inert, disease-free and reusable growing medium.

Horticulture & hydroponics
The granules are fired above 1,100 °C, which leaves a medium entirely free of weed seed, fungi and nematodes with no initial sterilisation.

Being chemically inert, it does not shift the EC or pH of the nutrient solution — decisive in hydroponics. At the end of a crop cycle the medium is washed, sterilised and used again.
