Perlite Fine or Medium Grade – Made in Australia
Perlite is a naturally occurring volcanic rock that has been super-heated to form lightweight, porous granules ideal for horticulture. This Australian-made perlite is available in Fine or Medium grade and comes in two convenient sizes: 5-litre and 100-litre bags. Used extensively in soil-free growing systems, seed propagation, and potting mixes, perlite improves aeration, drainage, and moisture control in a wide range of growing environments.
With its clean, sterile structure and neutral pH, perlite is an excellent component in blends for hydroponics, microgreens, and seed raising trays. Whether you’re conditioning heavy soil, growing herbs in containers, or managing moisture in a greenhouse, this product helps create a healthy root environment by maintaining airflow and reducing compaction.
