Vermiculite 100 Litres

Mineral silicate aggregate for soil less mixes. Vermiculite is a safe inert material, light in colour. When heated it expands (exfoliates) up to 30 times its original volume. The exfoliation process converts the dense flakes of ore into lightweight porous granules containing innumerable minute air layers. A 50:50 mix of perlite and vermiculite works extremely well as a sterile medium for all plants.
