Professional-grade 2 – 5mm horticultural perlite for improved drainage, aeration and healthier root development.
Growers Own Horticultural Perlite is a lightweight, pH-neutral growing media additive made from natural volcanic rock. Supplied in a generous 100L bag with a 2 – 5mm particle size, it helps create a lighter, more open growing medium with improved drainage and air space around developing roots.
Its porous structure makes Growers Own Perlite particularly useful for improving compost and potting mixes where additional aeration and drainage are required. It can help reduce compaction and maintain a more favourable root environment, making it a versatile choice for professional growers, nurseries, propagation and general horticultural use.
Why choose Growers Own Horticultural Perlite?
- 2 – 5mm horticultural grade – a versatile particle size for potting mixes, propagation and general growing media applications.
- Improves drainage – helps excess water move through the growing medium and reduces the risk of waterlogged conditions.
- Increases aeration – creates additional air space within compost and growing media to support healthy root development.
- Helps reduce compaction – maintains a lighter, more open structure within growing media.
- pH-neutral – can be incorporated into growing media without significantly altering its pH balance.
- Natural volcanic material – produced from naturally occurring volcanic rock.
- Lightweight and sterile – easy to incorporate into growing media and suitable for a broad range of horticultural applications.

What is Growers Own Perlite suitable for?
Growers Own Perlite can be mixed with compost, soil and other growing media where greater drainage, aeration or structural stability is required. Its 2 – 5mm particle size makes it suitable for a wide range of horticultural applications, including potting mixes, container growing, propagation and soil conditioning.
It is particularly useful where a growing medium is prone to becoming dense or compacted. Adding perlite creates additional pore space within the mix, helping air and water move more freely around the root zone while supporting strong, healthy root development.
How to use Growers Own Perlite
Mix Growers Own Perlite thoroughly through your chosen compost, soil or growing medium according to the drainage and aeration requirements of the crop. The amount required will vary depending on the existing growing medium and the plants being grown.
The 2 – 5mm grade can be incorporated into potting and propagation mixes to improve structure, or used when conditioning heavier growing media where additional drainage and air space are needed.
