Product Description

Product Description

Horticultural Perlite

Perlite is a soil conditioner and growing medium that isn't made from pearls, but is very light. It occurs naturally as an
amorphous volcanic glass with a relatively high water content. When this natural substance is heated to extremely high
temperatures (850-900°C), it expands substantially to become the commercial product perlite. 

Commercial perlite is extremely white due to the reflectivity of the bubbles in its structure, which also make it very lightweight.

Our Perlite is available in four sizes: fine 1-3mm, medium 2-4mm, and coarse 3-6mm, super coarse 4-8mm. 
Perlite is the perfect complement to soil, which can retain a lot of water. Perlite holds a film of air close to its surface and
creates air pockets no matter how wet the growing medium is.
Perlite is a common soil amendment that helps stimulate plants growth. The increase in drainage helps prevent overwatering and
nutrient buildup, while increasing root penetration and oxygen availability.

Application

Horticultural Perlite Application

Horticultural perlite is a lightweight, sterile, and pH-neutral volcanic glass that has been expanded under high temperatures.
It is widely used in agriculture and gardening due to its excellent drainage, aeration, and moisture retention properties.
 
Main Applications:
 
Soil Amendment:
Mixed with soil or compost to improve aeration and drainage, helping prevent root rot and promoting healthy root development.

Hydroponics:
Used as a growing medium for hydroponic systems, providing a stable structure with good air and water retention.

Seed Starting:
Ideal for germinating seeds. Perlite creates a light and airy environment, allowing young roots to grow freely.

Rooting Cuttings:
Used as a sterile medium for propagating plants from cuttings, ensuring minimal risk of disease and optimal moisture balance.

Greenhouse and Nursery Use:
Maintains consistent moisture and temperature in container mixes, making it a reliable component for commercial growers.

Lawn and Garden Care:
Helps to loosen heavy clay soils and enhance water penetration and retention in sandy soils.
Perlite is non-toxic, long-lasting, and environmentally friendly, making it an essential material for both amateur and professional growers.
