Ponics Stone™ Soilless Pumice Grow Media

Sourced from the world’s purest commercial deposit of white pumice, Ponics Stone™ is effective, economical, sustainable, and planting-ready—pour directly from the bag into your aquaponic or hydroponic grow beds.

Why Pumice Excells as a Soilless Grow Media. The key characteristics of pumice grow media include: Superior nutrient-holding capacity, customizable drainage rates (via grade blends), free-flowing gas exchange (oxygen and carbon dioxide) in the root zone, lightweight (due to its foamed-stone form factor), yet substantial enough to provide a stable bedding matrix to support thriving plants and stay put during irrigation cycles, enduring (lasting years in a properly designed and maintained system), a nature-made (volcanically calcined) sustainable resource.

Ponics Stone™ is available in four grade sizes to allow one to customize the pumice grow media to the specific needs of the crop and the aquaponics or hydroponics system.
