HORTICULTURE GRADE PERLITE
Perlite is an alumino-silicate of volcanic origin, which when crushed and heated rapidly expands to form a white lightweight stable aggregate, possessing a closed cellular structure. Water is retained only on the aggregate surface and in pore spaces between aggregates - the result is a well-drained lightweight media, easy to handle and transport. The aggregates have good structural integrity and do not break down when utilized as a propagating media or in planting mixes, developing a near-ideal structural condition in growing and propagating media.
