Horticultural Perlite Introduction:

Horticultural perlite is a great material for improving soil in horticultural cultivation. Its particles have a honeycomb-like and alkali resistant. It is commonly used in agriculture, gardens, and flowers because of its good fertility, water retention, sterility, and breathability. By adding an equal amount of perlite to the clay, the soil's aeration can be increased several times, allowing the roots to come into contact with sufficient oxygen for respiration. Expanded perlite has stable chemical properties   and a neutral PH value, so it won't cause harm to plants. It's also a soilless cultivation medium and a specialized medium for cutting propagation, which can keep the soil water and breathable.


【 Item Name 】 Horticultural perlite, suitable for various soilless cultivation. It is a commonly used soil improvement medium


【 Product Usage 】 Perlite is a precious natural resource, lightweight, water holding, breathable, and rich in organic matter. The commonly used matrix formula for seedling cultivation is peat, perlite, and horticultural vermiculite (by volume) 3:1:1.


【 Product Characteristics 】 1. Perlite is a natural silicate mineral, which is an expansive material processed at high temperature. 2. The texture is loose and has a multi porosity structure (with a porosity of about 95%). The shape is irregular and the particle size is 2-4mm. 3. The water absorption capacity can reach 2-3 times its own weight, with good water permeability and breathability. It is an important substance for improving soil in horticultural cultivation and is increasingly widely used. Adding an equal amount of perlite to the clay can increase the soil's aeration several times, allowing the roots to come into contact with sufficient oxygen for respiration. 4. Stable chemical properties, no harm to plants, neutral pH value.


【 Package】 (Light knitted bags) about 6-8 kilograms; (Heavy knitted bags) about 11 kilograms.


【 Product Particle Size 】 Small particles, about 2-4mm, large particles, about 3-5m.


【 Application 】 Home gardening, green plant beautification, saline alkali land improvement, etc.


【 Physical and Chemical Properties 】 It is milky white at room temperature and has porous interior.


【 Product Features 】 Lightweight and breathable, high water absorption, and promoting root growth.


【 Usage 】 It can be used immediately after opening, without the need for secondary processing.


Usage Method:

Using a mixture of perlite, peat, and vermiculite can boost the chances of plants surviving, especially when used for cutting or mixed with other substrates like nutrient soil, soil, peat, or vermiculite. This combination can create an ideal medium for sowing, cutting, and cultivation.


Characteristics of Horticultural Perlite:

1. When saturated with water, the weight ranges from 450-600kg/m³ (usually around 1800 kg/m³ in soil), effectively solving the load problem of building structures.

2. The permeability coefficient is 200mm/hr, which can effectively avoid the harm of sedimentation.

3. The effective moisture content is as high as 45%, which can effectively intercept rainwater.

4. 100% pure inorganic cultivation substrate, stable physical and chemical indicators, and long-term cultivation of plants without the need for soil replacement.

5. The porosity of the product greatly promotes the growth and development of the virtual root system of plants, has an excellent fixation effect on trees, and overcomes the damage of tree main roots to building structures.

6. Clean and odorless, easy to construct, and convenient for maintenance.


Application for Horticultural Perlite:

1. Home gardening, horticultural perlite has the characteristics of cleanliness, environmental protection, and no odor, making it very suitable for indoor use in home gardening.

2. Green plant beautification, perlite can not only exert good physical properties, but also play a good role in promoting green plant beautification and visual senses. Gardening nurseries, lawn construction, tree transplanting, roof gardens, underground parking lots, ecological roads and bridges, sunshine halls, courtyard potted plants, sports grounds, and saline alkali land improvement, as well as suitable for soilless cultivation of flowers and trees and pollution-free economic plants, are excellent plant materials for ecological horticulture cultivation.


Advantages to using Expanded Perlite to plant flowers and plants:

1. The insulation effect is good, and the water absorption rate of perlite is higher than that of planting gold stone, which has a good insulation effect. 1cm thick perlite can keep the insulation plant material moist for 7 days.

2. Cleaning does not breed fungi, which is better than water moss.

3. It can maintain good breathability, high water absorption, and promote root growth of the plant material.
