Lightweight horticultural perlite is a naturally occurring volcanic mineral that has been heat-expanded into small white granules. This high-quality perlite improves soil aeration and drainage, supporting strong root growth in a wide range of plants. It is ideal for mixing with compost or soil in pots, containers, raised beds and garden borders.

When added to soil, perlite keeps it light and airy, reducing compaction and allowing roots to breathe freely. It helps prevent waterlogging by letting excess water drain while still retaining essential moisture. This balance makes it suitable for houseplants, vegetables, seedlings and greenhouse use.

Available sizes: 1,5 and 10 Litres

Key Features

  • Improves soil aeration and drainage for healthy root growth
  • Ideal for mixing with compost or soil in pots, raised beds and borders
  • Prevents soil compaction and supports stronger plant development
  • Retains moisture while allowing excess water to drain away to avoid root rot
  • Suitable for houseplants, vegetables, seedlings and greenhouse use

How Lightweight Horticultural Perlite Improves Soil Aeration And Drainage

Perlite keeps soil open and free-flowing, allowing plant roots to access oxygen and nutrients more effectively. Unlike heavy materials such as sand or grit, perlite maintains a light structure while improving water movement through the soil. This makes it easier to work with, especially in containers and hanging baskets where weight is a factor.

Why Gardeners Choose Perlite Over Vermiculite

When comparing perlite vs vermiculite, both help with soil structure but in different ways. Perlite is better for plants that prefer free-draining conditions as it reduces water retention while keeping soil aerated. Vermiculite holds more moisture, making it more suited to plants that require consistently damp growing media. Many gardeners combine both depending on the plant’s needs.

Using Perlite In Compost And Potting Mixes

For most plants, mix 25% perlite with 75% compost or soil to create a balanced growing medium. For succulents and cacti, increase perlite content to 50% for sharper drainage. This mix prevents root rot and supports long-term plant health by maintaining a balance between moisture retention and drainage.

Perlite For Seedlings And Cuttings In Pots

Perlite is particularly useful for germinating seeds or propagating cuttings. Its structure holds moisture evenly without causing waterlogging, helping young roots establish quickly. Because perlite is sterile, it reduces the chance of soil-borne diseases affecting delicate seedlings during early growth stages.

Questions And Answers

Can I use perlite alone without compost or soil?

Yes, perlite can be used on its own for rooting cuttings and starting seeds, but most plants benefit from it being mixed with compost or soil.

Does perlite break down over time?

Perlite is stable and does not decompose, so it will remain in the soil mix for many years.

Can perlite be reused?

Yes, it can be washed and sterilised before reuse to remove any old roots or plant material.

Is perlite safe for all types of plants?

It is safe for most plants, though the ratio should be adjusted depending on whether the plant prefers moist or well-drained conditions.

How should perlite be stored?

Keep it in a dry, sealed bag away from damp areas to prevent moisture absorption before use.

Good product. Fits fine. This is not a Toyota part so Air Flow Arrows on filter should face down in a 2015 Toyota Rav4.

It fits, but just barely, so it's good that it is sturdy

First and foremost, this part is a fairly poor copy of the OEM part. It's close enough to look good from about 20 feet away, but on close inspection, it has gaps all around. It doesn't follow the curve of the opening properly, and the contours aren't quite right, making it so the outer top corners aren't recessed the way they are supposed to be (see pictures). Some of the tabs don't interface with their mating surfaces because the part is about 5mm too small in the y-axis (see picture). That said, after ordering another similar knock-off, this one is the better of the two. The matte finish is truly matte. The grill slats are thick and beefy, like OEM. The tabs are stout and flexible, not brittle. After much fussing with installation, you should be able to bend your hood tabs (not that you should have to) so all tabs will lock in place. The hardest part for me was getting the outboard-most tab to properly snap in, since the outer top corner of each grill doesn't sit flush inside the recessed relief where it's supposed to sit.
