Perlite is a lightweight, sterile volcanic mineral that dramatically improves aeration, drainage, and root development in soil and growing media. Ideal for propagation, potting mixes, hydroponics, and soil conditioning, Perlite expands when heated to create a rigid, porous structure that supports healthy root systems and reduces the risk of overwatering.

Available in both Standard and Super Coarse grades, this 100L bag of Perlite is suitable for a wide range of horticultural and landscaping applications. Standard Perlite is ideal for seed sowing, bedding plants, and compost mixes. Super Coarse Perlite provides maximum drainage and structure for trees, shrubs, large pots, and professional-grade compost formulations.

Trusted by nurseries, landscapers, and commercial growers, Perlite is a go-to additive for ensuring strong root growth and consistent moisture control in a variety of planting environments.
