LECA Expanded Clay

LECA (Light Expanded Clay Aggregate) is a versatile growing medium known for its exceptional properties in horticulture and agriculture. It is created through a unique process involving the blending of sodium and clay, followed by high-temperature firing in a rotary kiln. The result is a collection of lightweight ceramic granules with a durable ceramic shell and a porous core.

One of LECA's key attributes is its round pellet shape, which features distinctive "honeycomb" spaces within each pellet. These spaces serve multiple functions, including efficient nutrient absorption and gradual release to the plants. Furthermore, these spaces facilitate oxygen access to the plant roots, a vital element in hydroponic systems.

Our inventory includes various sizes of LECA to accommodate different growing setups. For larger net pots and Dutch buckets, 8 – 16 mm expanded clay balls are a suitable choice. If you have smaller-sized net pots (e.g., 50 mm, 75 mm, or 200 ml), the 2 – 10 mm expanded clay balls are ideal. Additionally, we offer 8 -10 mm LECA, which is versatile and can be used for medium to larger-sized net pots, grow beds, Dutch buckets, and more.

The lightweight, rounded clay balls in various sizes are excellent for hydroponic applications, especially systems that involve ebb and flow or drain-to-waste setups. These clay balls enable fast water flow between them, ensuring that the roots receive a consistent supply of nutrients while remaining well-oxygenated. This optimal environment results in healthy and vibrant root and plant development.

LECA offers several advantages, including its lightweight nature, high permeability, durability, and remarkable sound and thermal insulating properties. As a result, LECA serves as a versatile aggregate suitable for a wide range of applications.

Please note that it's essential to flush or rinse the product before use, the shape and colour may vary.

In summary, LECA is a lightweight expanded clay aggregate with unique properties that make it a preferred choice for horticultural and agricultural applications. Its consistent quality, pH neutrality, stability, durability, and resistance to fungi and insects make it a reliable choice for enhancing plant growth and productivity.
