A new expanded clay variant for hydroponics

For hydroponics, HAWITA has launched expanded clay, measuring between 8 and 16 millimetres thick, on the market. The raw material is fired clay obtained from natural sources. The expanded clay is chemically neutral, clean and odourless, and also has a special surface for hydroponics. Being fired at more than 1,200 degrees causes the clay to gain so-called capillary properties, which bring about an ideal air-to-moisture ratio. The FruhstorferErde expanded clay is breathable and water-regulating too.
