Large, lightweight granules
Particle size is the defining feature that distinguishes this perlite from finer grades.

A lightweight, inert material that opens the substrate structure without adding nutrients. The large 5–15 mm granules create more space for air and the release of excess water, while helping the mix resist compaction.
The large particle size is not intended to behave like fine sand or soil. It creates larger gaps within the mix so the structure remains more open.
Particle size is the defining feature that distinguishes this perlite from finer grades.
The large granules naturally create gaps between the other materials and support a better-aerated root zone.
Within a properly designed mix, it helps excess water find an easier route to the base of the pot.
The coarse structure keeps the mix more open and reduces the tendency of finer ingredients to compress together.
Use it according to the role you need it to play: as a structural amendment, a component in a custom blend or on its own as an inert propagation medium.
Mix it evenly into a substrate that needs a more open, less compact structure.
Combine it with the other materials in the mix according to the plant, the pot and the watering method.
It can be used on its own for propagation, with moisture and nutrition managed separately.
The appropriate amount depends on the requirements of the species, the composition of the base mix, pot aeration, temperature and watering method. Adjust the structure of the mix to the actual growing conditions.
The aim is to distribute the material throughout the mix rather than form an isolated layer.
Check how dense the existing substrate is and how quickly it releases water.
Distribute the granules throughout the full volume of the mix without excessive pressure that could crush them.
Check the runoff and drying time, then adapt care to the plant's needs.
Contains 100% expanded perlite in 5–15 mm granules. The bag is resealable and recyclable.
Reseal the bag securely after use to prevent contamination and preserve the structure of the material.
An aerated pot for the finished mix and a scoop for more controlled handling of the materials.

Clear, aerated pots with side slots and an anti-spiral structure for organised aroid growing.

No. It is an inert material and is not a source of nutrition. Fertilising must be covered by the rest of the growing system and the plant's needs.
Yes, it can be used on its own as an inert propagation medium. Because it does not provide nutrients, moisture and nutrition must be managed separately.
It is particularly useful for aroids, succulents and other plants that need a well-aerated, fast-draining substrate.
There is no universal percentage. The amount depends on the plant, the base substrate, the pot, temperature and watering method. The goal is a structure suited to the actual growing conditions.
Store it in a cool, dry place and reseal the bag securely after use to prevent contamination and preserve the structure of the material.
