Ceramic granules - expanded clay 8-16mm 5L

Expanded clay (ceramic granules) 8-16mm is an inert hydroponic substrate of high quality. As a basis serve clean and salt-free types of foams, which burn in an open oven until they get their characteristic irregular form. Ceramic granules have a wide application that allows you to regulate the nutritional value. This substrate is suitable for a variety of cultivation methods and is particularly suitable for the re-use system.
