Product Description

1.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.
 

 

Horticulture Perlite Usage

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

5.Expanded Perlite's Applications:

1.1-3/2-4/3-6mm is widely used in horticulture, urban greening to improve the soil porosity and ventilation, and withhold water and fertilizer.

2.Widely used in oxygen manufacturer and freezer as well as insulating layer in transporting liquid oxygen and hydrogen.

3.Used to filter liquor, oil, medicine, food and dirty water.

4.Used as filling and dilating agent in rubber, painter and plastic, etc.

5.Used as catalyst in explosives.

6.Used to absorb floating oil.

7.Mixed with different adhesive to make templates of different sizes and functions.

8.Used as in large volume as insulating layers in industrial smelting.

 

• 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.
