Agriculture and Horticulture Grade Growing Medium Expanded Vermiculite
Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire resistant, and odorless.
In lightweight plaster and concrete,vermiculite provides good thermal insulation. Vermiculite can absorb such liquids as fertilizers, herbicides, and insecticides, which can then be transported as free-flowing solids.

Chemical composition of expanded vermiculite:
Most applications for vermiculite use an exfoliated (heat expanded) form of the mineral. In general, coarser grades of vermiculite are used as loose fill insulation and in horticulture. Finer grades are used in wallboard and plasters and for animal feeds and fertilizers.
Vermiculite for Gardening
Vermiculite has a high cation exchange capacity which facilitates the uptake of nutrients in plants, one of the reasons it's used in potting mixes.
It loosens the soil so that the roots can easily reach down and grow through the soil.
Greenhouse/Vermiculite is well established as a growing medium. It is most commonly used in compost formulations, usually in combination with peat or coir. Vermiculite/peat or coir compost formulations provide ideal conditions for plant growth. The presence of vermiculite particles in the compost aids aeration, improves moisture retention and promotes the steady release of added fertilisers, whilst the vermiculite itself contributes potassium, magnesium and a number of minor elements.
