Piatra ponce (pumice) 5-12 mm

Pumice stone is used in a mixture with the soil to increase the water absorption capacity and aeration of the substrate, which gives plants access to water for a longer period of time, ensuring very good drainage.
Pumice is a natural substrate derived from volcanic rock. It is formed from gas-rich lava that solidifies in water.
