Lightweight expanded-volcanic perlite that opens up heavy potting soil so water drains freely and roots get the air they need. Mix it into seed-starting blends, succulent and cactus soil, or any container mix that stays too wet. The coarse grade resists compacting over the season. Blend up to one third by volume for fast-draining pots, less for general use.
