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 an ideal surface structure. Hydroton® brand expanded clay is semi-porous and generally does not float like other products can. For best results, rinse all expanded clay before use. It is reusable as long as it is thoroughly cleaned between uses. 50 liter bags feature an easy pour spout. Size specification is 8-16 mm. W e have been told the product floats, contact us with any questions.
The product is sold by Liters /Volume, not in Pounds /Weight The product varies in weight from bag to bag and pallet to pallet. Some pieces are bigger and hollow and others are smaller and dense, which is why this product is sold by volume rather than weight.
