Description
Perlite is a form of glass; specifically a volcanic glass that is mined and then heated in big ovens until it ‘pops’ into a round, white material that’s used in seed-starting and potting mixtures to lighten the soil, allow more air around the roots of plants and to both help retain water and improve drainage.
A lot of people think that those little white balls are a form of Styrofoam-type artificial substance—but they are a mined mineral popped into little balls.
Available in 6L.
