Description

Vermiculite medium is lightweight, density approximately 100kg/m³.  It is chemically and biologically stable, free from pests, weeds and diseases. It has a neutral pH (6.0-7.0) and is an excellent insulator, retains water, has a high porosity, and high nutrient buffer capacity. 

Vermiculite Medium is the most popular grade of vermiculite, and is widely used for seed covering and for improving composts. It has good water holding and nutrient buffering capacity combined with excellent insulation properties making this an excellent seed covering media.  If used in composts it should be used where there is a requirement to improve aeration without impacting adversely upon water capacity or water retention. 

Use at up to 50% by volume as a compost amendment.
