50L Hydro Clay Balls are an ideal substrate for plant growth in hydroponic systems.
Hydro Clay is a German made, premium quality substrate consisting of spheres of expanded clay, which provide inert structural support for plant roots in hydroponic systems. The consistently round shape (8-16mm) provides a high degree of aeration, which ensures extremely quick drainage and unimpeded root growth. The clay balls are also less susceptible to pest and disease than other solid substrates.
Perfect for efficient drainage during plant growth.
