Perlite is a lightweight expanded volcanic mineral amendment that helps improve drainage, aeration and root airflow in potting mixes. The 2-4mm grade is a finer perlite size that is commonly used for seed germination, cuttings, propagation, small pots, herbs, vegetables and soilless growing mixes. It helps loosen compact media and allows plant roots to receive better oxygen while reducing the risk of overly dense potting mixes. Perlite is best used by mixing it with other growing media. Avoid using it alone for long-term potting, as it does not hold enough nutrients by itself and may dry out too quickly for some plants.
