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 & most often does not glide like other products can. For best possible 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. The dimensions specification is 15–25 mm.
