Perlite is expanded volcanic glass. The glass is heated to 1600°F (871°C) and puffs/pops, to create very lightweight, porous particles. Several properties make perlite a popular amendment for various types of potting medium, as well as an excellent propagation medium on its own.
- resists soil compaction
- encourages aeration
- large surface area
- improves drainage
- promotes healthy root growth
Available in two particle sizes (see pictures for scale).
