Luwasa Expanded clay

Luwasa clay pebbles, kidney-shaped with a diameter of 8-16 mm. The Luwasa clay pebbles are made from low-salt clay types, which means they require less washing. They have a relatively low weight. They do not store water or nutrients but instead direct them to the plant roots through their surface. The structurally stable clay pebbles are baked at high temperatures in drum kilns. Another advantage of Luwasa clay pebbles is that their irregular shapes provide more stability for the plant.
