Vermiculite is one of the world's most unique minerals. Scientifically it is composed of hydrated Magnesium Aluminium Silicate, it has characteristics of lightweight, inorganic (incombustible), compressible, highly absorbent and non-reactive. Vermiculite (Wikipedia) is used in thousands of applications, and is ideal for seed covering & mixing with compost, soil and hydroponic mediums. We highly recommend mixing at a 50 - 50 ratio with Perlite for Autopot systems. At a 30 - 70 ratio (vermiculite - perlite) it creates a media that is more water-absorbent than perlite and will allow you to water less.
