Mother Earth® Hydroton® brand expanded clay is a unique, lightweight expanded clay aggregate made in Europe. 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 an ideal surface structure. Hydroton® brand expanded clay is semi-porous and generally does not float like other products can. For best results, rinse expanded clay before use. It is reusable as long as it is thoroughly cleaned between uses. Because expanded clay is a natural mined product, you may see variances in shape, color, etc., due to the variances in the source material.
