What Is Vermiculite: Tips On Using Vermiculite Growing Medium
Vermiculite is the name of a group of hydrated laminar minerals (aluminum-iron magnesium silicates) which look like mica. Horticultural vermiculite is processed with massive heat that expands it into accordion shaped pellets composed of multiple layers of thin plates. It will not rot, deteriorate, or mold and is enduring, odorless, non-toxic, and sterile. Vermiculite is generally a neutral 7.0 pH, but is dependent upon the source from around the globe and its reaction is alkaline. It is very lightweight and mixes easily with other mediums.
