Leca® Lightweight Aggregate Concrete (4-10mm) is mainly used as an additive in industrially manufactured Concrete. One of the primary benefits of using Leca® Lightweight Aggregate Concrete in lightweight concrete production is its reduced density. The aggregate's unique porous structure significantly decreases the overall weight of the …
LECA will give your plants the right amount of water. That's because the LECA substance absorbs water directly from roots, but leaves air so that the plant doesn't suffocate. The clay pellets will soak up water and expand. Then, the LECA balls release some of the water gradually so that the plant always receives a steady supply.
Whilst LECA® LWA is a simple product, our solutions are innovative. Alone, it is one single expanded clay pellet, but when combining the pellets into an aggregate, the civil engineering possibilities become endless - whether it is lightening road and railway embankments, insulating and filling of swimming pool surrounds, reducing pressure …

LECA, or lightweight expanded clay aggregates, are small clay balls that allow space for necessary plant oxygen and soak up excess water. While they don't provide any nutrients the way soil would, they have other benefits that may make it worth the extra expense (and special fertilizer).
LECA is short for lightweight expanded clay aggregate, a clay-based growing medium that supports hydroponic gardens. The balls of clay allow air and water to travel through. However, not all plants do well when grown in LECA, so don't disqualify soil as an option!
