What are Hydroton clay balls?
Hydroton clay balls, also known as expanded clay pellets, hydroton, or LECA (Lightweight Expanded Clay Aggregate), are small, lightweight, and porous balls made from clay. They are typically brown or reddish and are characterised by their exceptional water retention and drainage properties. Hydroton clay balls are widely used in hydroponic systems, container gardening, and as a growing medium in various applications.

How Do Hydroton Clay Balls Work?
The science behind Hydroton clay balls lies in their unique structure and properties. Here’s a closer look at how they work:
Water Retention and Aeration
Hydroton clay balls have a porous structure that allows them to retain water efficiently. When soaked in water, the clay balls absorb moisture, creating a reservoir that plants can draw from. However, they also have excellent aeration properties. The air pockets within the clay balls ensure that the roots receive adequate oxygen, preventing waterlogging and root rot, which can be common issues in traditional soil-based gardening.
Capillary Action
The capillary action of Hydroton clay balls helps distribute water and nutrients evenly throughout the growing medium. As the roots of the plants reach out into the clay ball-filled space, they can access water and nutrients through the capillary channels, promoting healthy growth.

pH Neutral
Hydroton clay balls are pH neutral, which means they don’t significantly affect the pH of the growing environment. This allows for greater control over the pH levels of the nutrient solution or soil mix.
Stability and Support
Hydroton clay balls’ stability and support to plants’ root systems are noteworthy. They anchor the plants securely and provide a consistent base for root growth, preventing them from becoming tangled or overcrowded.

Reusable and Sustainable
Hydroton clay balls are reusable, making them an environmentally friendly option. After a growing cycle, they can be cleaned and sterilised for use in subsequent plantings. This reusability reduces waste and the need for frequent replacement.
Applications of Hydroton Clay Balls:
Hydroponic Systems
Hydroton clay balls are a staple in hydroponic systems, where plants are grown in nutrient-rich water without soil. The balls support the plants and allow their roots to access water, nutrients, and oxygen effectively.
Container Gardening
When used as a part of a soil mix in pots and containers, Hydroton clay balls improve drainage, prevent compaction, and enhance aeration.
