Root Aeration Granules for Potting Mix
Description
Perlite is an amorphous volcanic glass with naturally high water content. When heated to 850–900°C, it expands 7–15 times its original volume, creating lightweight, brilliant white granules. This unique structure makes perlite ideal for improving soil aeration, drainage, and root health.
Properties
- Expands significantly when heated, forming reflective, porous granules
- Density: raw perlite ~1100 kg/m³; expanded perlite ~30–150 kg/m³
- Neutral pH (6.5–7.5), sterile, and disease‑free
- Acts as an insulator against extreme soil temperature fluctuations
- Lightweight, odorless, clean, and safe to handle
Characteristics
- Improves aeration and drainage in pots and mixes
- Makes moisture and nutrients readily available to plants
- Inorganic and long‑lasting — does not deteriorate
- Supports healthy root development and prevents soil compaction
Applications
- Plant rooting and propagation
- Seed starting medium
- Hydroponic growing systems
- Soil conditioning for pots and garden beds
- General growing medium for indoor and outdoor plants
Size
Granule size: 1–5 mm
Complementary Products
For balanced plant care, combine perlite with moisture‑retaining vermiculite to create mixes that support both aeration and hydration. You can also explore our range of growing media such as cocopeat and compost to build the perfect foundation for seeds, pots, and hydroponics.
