Professional products Raw materials Perlite
Expanded perlite for drainage and custom mixes in nursery production.
Arber Perlite is a mineral raw material of volcanic origin, thermally expanded to a granulometry of 2–6 mm. It is a lightweight, draining, and chemically inert component. It improves the water profile of Pro substrates and supports the formulation of custom mixes in seedling production and nursery. Available in 100 L bags.

Features
In the nursery, Arber Perlite speeds up drying between irrigations and reduces waterlogging around roots in sensitive species. Its porous structure, developed through controlled thermal expansion, maintains consistent drainage over time without compacting during the growing cycle. Available in 2–6 mm granulometry in 100 L bags.
It is a preferred component for improving the water profile of Pro substrates. Added at calibrated rates to peat mixes and other components, perlite reduces the risk of root asphyxia. Chemically inert and free of nutritive components, it does not interfere with the grower's fertilisation plan. Its low weight reduces the overall weight of containers at the same volume — an operational advantage for handling in the nursery.
Arber Perlite is natural and free of pathogens and toxic substances. It comes from a European supply chain with a controlled thermal expansion process. Consistent production and regular deliveries make it a reliable reference for professional nurseries planning cycles at significant volumes.
Why choose it
- Volcanic glass expanded at controlled temperature. Porous structure maintains consistent drainage over time.
- Granulometry 2–6 mm: rapid lightening and drainage in the container, without compaction during the cycle.
- Neutral pH and zero EC: a neutral addition in any mix.
- Improves root oxygenation in long-cycle substrates.
- 100 L bag: easy dosing in the nursery and on site.
Why use it
Lightens and drains rapidly
Granulometry 2–6 mm: adds air porosity and speeds up drainage in any substrate mix.
Improves root oxygenation
Stable porous structure: in long-cycle substrates it prevents compaction and preserves root vigour.
Neutral addition in any mix
Neutral pH and zero EC: you can add it without altering the chemical profile of the base substrate.
Compatible with all crops
Universal for seeding mixes, propagation, repotting, and specific formulas, in nursery and greenhouse.
