Course Horticultural Grade Vermiculite

Course Horticultural Grade Vermiculite     4 CFT.  Bag

Horticultural-grade vermiculite has become a mainstay as a component of soil less growing mediums, as a soil amendment and in many other horticultural uses.
Vermiculite is the name given to a group of naturally occurring hydrated laminar minerals similar to mica. When processed in special furnaces, the mineral exfoliates (or expands) into the accordion-like layered particles familiar to many as a part of soil-less growing mixes. The processed product is sterile, permanent, odorless and non-toxic. It has the highly desirable characteristic of being lightweight and the capability of moisture and nutrient retention.  Natural occuring product.
