Siro Hydroton

SIRO® HYDROTON is expanded clay, especially developed for plants. A unique manufacturing process uses selected raw materials, producing 8 - 13mm optimized spheres with an ideal, homogeneous porosity, which ensures adequate capillarity for the plants' needs. Its texture improves drainage and aeration of heavy substrates/soils, preventing rotting of the root system of the plants. It is an inert product, free of bacteria and any toxic substances.
