The original Hydroton Brand expanded clay is a unique, lightweight expanded clay aggregate made in Germany. This natural clay is mined, formed into pellets, then kiln fired at high temperatures to cause the clay to expand into tough, lightweight balls. Clay naturally has balanced capillary action, with a great surface structure. Hydroton Brand expanded clay is semi-porous & normally does not drift like other products can. For absolute best results, rinse all expanded clay before use. It’s reusable so long as It’s thoroughly wiped clean between uses. 50 liter bags feature a very easy pour spout. Size specification is 8-16 mm.
