Size

Coarse Perlite – 3–15mm

Aeration • Drainage • Lightweight Structure

Coarse Perlite is a sterile, lightweight soil amendment made from naturally occurring volcanic glass. Heated at high temperatures, it expands into a porous, inert material that dramatically improves aeration, drainage, and soil structure—creating a more breathable root zone and helping prevent compaction.

This coarse 3–15mm grade is especially useful in mixes where airflow and fast drainage are key. It blends easily with other substrates to create well-balanced, free-draining soil that supports vigorous root growth and moisture regulation—indoors or out.

🌿 Benefits

  • Improves root zone aeration and drainage

  • Helps break up dense or compacted mixes

  • Sterile, odorless, and pH-neutral (~7.0)

  • Lightweight and easy to blend

  • Derived from a natural volcanic source

  • Suitable for soil mixes, propagation, or hydroponic use


🌱 How to Use

  • Soil Mixes – Blend with coir, peat, compost, or bark to create a well-structured growing medium

  • Propagation – Use alone or with other media for seeds or cuttings

  • Hydroponics – Functions well as a base or additive in soilless systems

⚠️ Wear a dust mask when handling dry perlite to avoid inhaling fine particles.
