Horticultural coarse vermiculite

1.What is horticultural vermiculite
Horticultural vermiculite is a light, absorbent material that is chemically inert and odorless. It is made from flakes of a mica-like hydrated silicate of magnesium-aluminum-iron. The flakes are flash heated to 900 degrees centigrade. Water quickly evaporates as the vermiculite expands like an accordion. This process, known as exfoliation, balloons the flakes to twenty times their original size. With an essentially neutral pH of 7.0, horticultural vermiculite helps with soil aeration and retains moisture, fertilizers, other nutrients and plant treatments.

2.Horticultural vermiculite Benefits
Horticultural vermiculite is versatile, clean and sterile. While its neutral pH of 7.0 trends toward alkaline because of carbonates in the product, it does not have the pH lowering effect of peat. When combined with peat or composted pine bark, the resulting mix provides faster root growth. Because of its expanded size and light weight, it helps aerate mixes while retaining moisture and nutrients. Horticultural vermiculite is also used to bulk up mixes and lessen compaction.
