Perlite

Perlite is a lightweight, porous volcanic mineral commonly used in potting mixes and soil amendments to improve aeration and drainage. When heated, perlite expands into small, white, sponge-like particles that help prevent soil compaction and promote healthy root development. Perlite is commonly used in container gardening, hydroponics, and seed starting to create a well-draining and aerated growing medium.
