Liaflor® Hydroculture Natural Clay Granulates are a pure and high-quality natural product. The reddish-brown ceramic and purely mineral clay granulate are manufactured in an environmentally friendly process and does not pollute the environment when disposed of. The clay is expanded whilst it is fired at 1200 °C in a rotary kiln and then screened out. This makes it a unique quality product with optimum properties and specific benefits, such as its low weight, high water retention and durability as well as its good root grip.  5L bag.
