Perlite – Airy Structure, Excellent Drainage and Ideal for Worm Composting and Propagation Soil

Perlite, the expanded volcanic rock with an exceptionally light and porous character, is an indispensable soil improver for both professional growers and hobby gardeners. This natural product ensures optimal aeration, improved drainage and a stable growth environment for roots, worms and microorganisms. Available in 2, 10 and 25 liter paper bags, or in a 1000-liter big bag. Suitable for organic use. Brand: Franky’s Flora.

What is Perlite?

Perlite is formed from obsidian, a volcanic glass containing small amounts of water. When heated to about 900 to 1200 degrees Celsius, it expands explosively as the trapped water vaporizes. This creates a white, granular material with an open honeycomb structure.

This unique structure makes perlite:

• extremely lightweight

• highly air- and water-permeable

• chemically inert

• pH-neutral

• fully mineral and sustainable

Thanks to these properties, perlite is ideal as a soil improver, lightweight substrate component and professional propagation material.

Why Use Perlite?

1. Improved Drainage and Aeration

Perlite creates air channels in the soil, preventing root rot and improving soil structure. It is the best choice for heavy, compacted or wet soils. Worms benefit from the improved aeration and move more easily through the substrate.

2. Ideal for Sowing and Propagating

The granular texture prevents seedlings from collapsing or suffocating. In propagation mixes, perlite provides the ideal balance between moisture and oxygen, resulting in faster and healthier root development.

3. Perfect for Worm Composting

Perlite holds moisture without compacting the substrate. This keeps worm compost airy and stable, supporting an active and healthy worm population.

4. Suitable for Hydroponics

Perlite can be used as a standalone growing medium or mixed with coconut fiber or other substrates. It supports roots, retains water and optimizes oxygen availability.

5. Environmentally Friendly and Safe

Perlite is natural, inert, non-toxic and fully recyclable. It contains no chemical additives and is suitable for organic cultivation.

Applications of Perlite

Horticulture

• Soil improvement: enhances drainage and aeration in potting mixes and garden soil.

• Seed and propagation soil: prevents compaction and promotes root growth.

• Potting mix component: ideal for houseplants, vegetable gardens and container plants.

Hydroponics

Use perlite as a standalone medium or as part of a substrate blend.

Industry and Construction

• Thermal and acoustic insulation.

• Lightweight concrete: reduces weight and improves energy efficiency.

Dosage and Mixing Ratios

Soil Improvement

Mix 10 to 30 percent perlite into existing soil to improve drainage and aeration.

Seed and Propagation Soil

Mix 1:1 with worm castings for optimal root development.

Hydroponics

Use perlite as a standalone medium or mix it with coconut fiber, clay pebbles or other substrates.

Perlite vs. Vermiculite – What’s the Difference?

Choose perlite when drainage, aeration and stability are the priorities.
Choose vermiculite when maximum moisture retention is desired, such as during seed germination.
