Higromite

Higromite is the only growing medium of its kind in the world. Higromite is mined from volcanic deposits colonized by protozoa in freshwater lakes millions of years ago. These deposits produce the best natural balance of organic, major and trace elements. Higromite provides several advantages over expanded clay pellets, coco, & rockwool. It's high in Silica, ph neutral, & has the best moisture retention & release on the market today. Completely reusable, the varied shapes of the rocks promotes porosity, allowing more oxygen to reach the roots.
