45 Litres Decorative Clay pebbles 8-20mm uneven soil additive replacement Alternative Medium

Our expanded clay pebbles are an excellent organic growing medium that we highly recommend for both indoor and outdoor use with our pots and planters. Customers love them for their ability to enhance plant performance and extend the lifespan of pots. They work particularly well in flood and drain and dripper systems.

These clay pebbles are created by heating clay to a temperature of around 1,200 °C (2,190 °F) in a rotary kiln, causing the clay to expand. The result is a rough and highly porous medium that excels at retaining moisture, trapping air, and oxygenating nutrient solutions.

In addition to their fashionable and clean appearance, these pebbles offer numerous benefits to both pots and plants. Firstly, their high pore space provides excellent aeration and moisture retention simultaneously. This promotes root growth by keeping the roots oxygenated and preventing waterlogging or clogging, which can harm the plant.

Using clay pebbles can accelerate plant growth by providing ample aeration to the root zone. They also create a sturdy support structure, ensuring unparalleled stability for your plants.

Our clay pebbles are pH stable and graded to measure 10-20mm in diameter. This irregular arrangement creates an advantageous environment for growth, offering ample drainage, oxygenation at the root zone, beneficial bacterial growth, and root binding for superior stability.

These pebbles are 100% natural and organic, and they can be washed and reused if you decide to repot your plants.

Here's how to use them:

1. Start by adding a layer of clay pebbles to the base of your pot.
2. We recommend using approximately one-third of the soil capacity of your pot with the clay pebbles.
3. Add your preferred soil mix or compost on top of the clay pebbles, filling about two-thirds of the pot.
4. To avoid a muddy or dirty appearance when the soil is wet, leave around 10% of the pot's volume for a top layer of clay pebbles for decoration.

By following these guidelines, you'll create an ideal growing environment for your plants, with the clay pebbles providing excellent aeration, drainage, and stability.
