Vermiculite Fine (1.0-3.0mm) is used to improve aeration, water management, nutrient retention and exchange and has insulation properties in growing media. Vermiculite Fine is graded for horticultural use. It is lightweight, density approximately 100kg /m3, has a neutral pH (6.0-7.0), excellent insulation, retains water, and has a high porosity and high nutrient buffer capacity. Vermiculite Fine is widely used for covering fine seed during propagation and is also valuable in easing the water management of peat composts. The water holding capacity is comparable to moderately decomposed peat, but the majority of water is retained more strongly then in peat so it extends watering intervals. It also provides a nucleus for re-wetting which makes watering management much simpler. Nutrient buffering compliments this water buffering action and with high air content this is a very useful product as a growing medium, seed covering and compost amendment. Recommended use is up to 50% by volume as a compost amendment.
