Perlite Horticultural Grade Medium P35 – 10 Litres
Perlite Horticultural Grade Medium P35 is a lightweight horticultural soil amendment supplied in a convenient 10-litre pack. Made from naturally expanded volcanic rock, this premium-grade perlite is widely used by gardeners, nurseries and professional growers to improve compost structure, drainage and root development. With a particle size of 1–5mm and a water-holding capacity of approximately 275ml per litre, it helps create the ideal growing environment for a wide range of plants.
Why Choose Perlite Horticultural Grade Medium P35?
Perlite is one of the most effective materials available for improving growing media. Furthermore, it helps reduce compost compaction and improves aeration around plant roots. As a result, plants can establish more quickly and develop stronger, healthier root systems. It is also sterile, free from pests, diseases and weeds, making it ideal for propagation and container growing.
Improves Drainage and Aeration
The porous structure of Perlite Horticultural Grade Medium P35 creates air spaces within compost and potting mixes. In addition, it improves drainage while still retaining useful moisture for plant roots. Consequently, growing media becomes easier to manage and provides a healthier environment for plant growth.
Ideal for Seeds, Cuttings and Potting Mixes
This versatile horticultural perlite can be mixed into seed composts, propagation mixes and container composts. Moreover, it can be used at up to 40% by volume to improve aeration and drainage. It is particularly beneficial for rooting cuttings, growing houseplants, alpines, bonsai and container-grown perennials.
Suitable for Hydroponics and Container Gardening
Perlite Horticultural Grade Medium P35 is widely used in hydroponic growing systems and large containers. Additionally, it can replace sand or grit in many compost recipes while helping to create a lighter, easier-to-handle growing medium. Its neutral pH of approximately 6.5–7.5 makes it suitable for a broad range of plants.
Care and Handling
Perlite is a lightweight and crushable material. Before use, lightly dampen the product to minimise dust and make handling easier. Store in a dry location until required.
