Discover expanded clay in 10L 8-16mm, ideal for hydroponic cultivation. It has a porous internal structure that absorbs and releases water with nutrients as needed by your plant.

This substrate has a stabilized pH between 5.5 and 6.5, which is perfect for hydroponic cultivation. You can mix it with other substrates without any problem.

We recommend soaking the expanded clay in the nutrient solution 24 hours before transplanting in order to stabilize the pH.
