MOTHER Earth Hydroton Original Clay Pebbles

MOTHER Earth Hydroton Original Clay Pebbles are a must-have for indoor and outdoor plants. Made in Germany, these lightweight clay pebbles are created from natural clay that is mined, formed into pellets, and kiln fired at high temperatures. This process causes the clay to expand into tough and lightweight balls, making them perfect for hydroponic systems and other gardening applications. The Hydroton brand expanded clay is semi-porous, ensuring balanced capillary action and preventing floating. These clay pebbles are reusable and can be thoroughly cleaned between uses. With a size specification of 8-16 mm, they provide excellent drainage and aeration for healthy plant growth.
