Perlites are used for plant cultivation, to increase the propeties of the soil structure. Mixed with a plant medium that contains soil or
peat perlites make it lighter and enhance drainage system properties. Perlites are extraorinary stable thus maintaining their quality. They are free from germs ans develop a healthy air-water-relationship. Especially young plants are in need of perlites, since they stimulate their root development and growth.

- Total pore volume up to 95 Vol.%
- Water storing capacity up to 50 Vol.%
- Immediately reusable
- Totally stable
- Salt-free, free from nutrients and with a neutral pH value

Usage:
Mix about 10 - 35% perlites with the desired plant medium.
Attention: Product may release perite dust. We recommend to wear a (surgical) mask to prevent from inhaling dust particles.

Tip for use
Put a thick layer of perlites under a tray of your cuttings. That way you create a great for their root development.

What exactly are perlites?

Perlite is an amorphous volcanic glass that has a relatively high water content. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently.
When it reaches temperatures of 850-900 °C, perlite softens (since it is a glass). Water trapped in the structure of the material escapes and vapourises and this causes the expansion of the material to 7-16 times its original volume. The expanded material is brilliant white, due to the reflectivity of the trapped bubbles.
Unexpanded ("raw") perlite bulk density: around 1100 kg/m³ (1.1 g/cm³).
Typical expanded perlite bulk density: 30-150 kg/m³

Due to its low density and relatively low price, many commercial applications for perlite have developed. In the construction and manufacturing fields, it is used in lightweight plasters and mortars, insulation, ceiling tiles and filter aids. In horticulture it makes composts more open to air, while still having good water-retention properties; it makes a good medium for hydroponics. Perlite is also used in foundries, cryogenic insulations, as a lightweight aggregate in mortar (firestop) and in ceramics as a clay additive.
