Vermiculite is a magnesium rich, silicate mineral similar to mica. It is produced by high temperature treatment of vermiculite ore, which produces golden brown lightweight granules. It is sterile, non-toxic, incombustible, asbestos-free and easy to handle. Vermiculite aerates heavy clay soils and potting mixes. It has high water-holding capacity, and is ideal for seed raising. Comes in a 5L bag.

It offers several unique properties which make it an ideal growing medium including:

  • Inorganic, inert and sterile;
  • Free from disease, weeds and insects;
  • Excellent aeration characteristics;
  • Facilitates re-wetting of mixes;
  • Slightly alkaline;
  • High water-holding capacity;
  • Insulates and reduces temperature changes; and
  • Holds nutrients in a form readily available for the plant
