Made from an amorphous volcanic glass, it has a relatively high water content. The tiny channels suck water and nutrients up from a reservoir below into the upper layers of the medium, whilst maintaining drainage to keep air around the roots. KEY VALUES: Lightweight, sterile and incredibly effective as a growing medium. Also for mixing in soil or other composts to improve drainage. Often mixed together with vermiculite to make a cheap seedling and cutting medium.
