What is Perlite?

Perlite is a volcanic rock that has been heated to create a lightweight, porous material. It’s a popular choice for soil mixes because it improves drainage and aeration. Here are some of the key characteristics of perlite:

  • Lightweight

  • Improves drainage

  • Improves aeration

  • pH neutral

  • Sterile and free of pathogens
