Super Coarse Perlite, 4 Cu. Ft. Bag

The 37BPRL is a super coarse perlite. Perlite is a volcanic mineral that is capable of greatly expanding from four to twenty times from its original size when heated at around 1600° F. Upon expanding, the perlite becomes lighter in weight and capable of absorbing exterior moisture from a particle. Due to its low density following processing, this product is suitable for horticultural purposes ...

Pearlite

Pearlite is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (87.5 wt%) and cementite (12.5 wt%) that occurs in some steels and cast irons. During slow cooling of an iron-carbon alloy, pearlite forms by a eutectoid reaction as austenite cools below 723 °C (1,333 °F) (the eutectoid temperature). Pearlite ...

Perlite

Reusing perlite without processing to grow successive crops is potentially risky because of media compaction, salt buildup, and pest contamination (Hanna and Smith, 2002). Replacing used perlite with new media to raise successive crops is costly, and recovering the expense by selling the product at a higher price may not work well in a competitive market.
