Grade 3 Exfoliators Vermiculite is a course light weight medium.
Vermiculite is part of the phyllosilicate group of minerals and is known as hydrated phlogophile mica.
Like perlite, vermiculite expands when heated to create a porous and light weight substance with excellent thermal and water holding properties.
It has a higher water holding capacity then Premium Perlite and can thus be watered less often.
