Dense, compacted soils can choke roots, leading to slow growth and nutrient deficiencies. Our Perlite solves this. Made from naturally occurring siliceous rock, it undergoes a meticulous kilning process (much like popping popcorn!) at 1600° F. This expansion creates an incredibly porous, lightweight material with exceptional physical properties. The result? A perfectly sterile growing media with a naturally neutral pH of 7.0, making it an ideal amendment that won't disrupt your existing nutrient program or soil chemistry. Its unmatched ability to add porosity is why it's a top choice for soil aeration and soilless mixes.
