1.The Introduction of Horticultural Perlite:
Horticultural Perlite is a naturally occurring volcanic rock. When heated at high temperatures, the perlite sand "pops up" and expands 7 to 15 times its original volume. The resulting lightweight particles are composed of microscopic spheres with a porous fracture surface that promotes plant growth. This allows ventilation and drainage of the root system and provides water and nutrient retention.
Horticultural Uses for Expanded Perlite:
1)Propagation of seedlings and cuttings 2)Soil conditioning 3)Hydroponics 4)Roof deck gardens and eco-roofs 5)Nursery stock 6)Hanging baskets 7)Turf enhancement 8)Newly planted trees and plants

• Light weight Expanded Perlite does not crush fine stems or root systems, making it ideal for growing delicate plants such as lettuce.
• Coarse Horticultural Perlite provides aeration and drainage, yet retains and holds substantial amounts of water that it releases when needed.

• The water-holding ability of Expanded Perlite also increases the nutrient holding capacity when water-soluble fertilizers are used.
• Can be used by itself, mixed with topsoil or potting soil, or any other sterile media for drip or passive hydroponic systems.
Normally, the expanded perlite is packed in 100L/bag. We also have Jumbo bag or add pallet.
