The original Hydroton brand expanded clay is a unique, lightweight expanded clay aggregate made in Germany. This natural clay is mined, formed into pellets, then kiln fired at high temperatures to cause the clay to expand into tough, lightweight balls. Clay naturally has balanced capillary action, with an ideal surface structure. Hydroton brand expanded clay is semi-porous and generally does not float like other products can. For best results, rinse all expanded clay before use. It is reusable as long as it is thoroughly cleaned between uses. Size specification is 8-16 mm.


LECA has a variety of benefits for plants, including:

1. Excellent drainage: LECA is highly porous and allows for excellent drainage, which is important for preventing water logging and root rot in plants.

2. Good aeration: The porous nature of LECA also provides good aeration to plant roots, allowing for the exchange of gases and better nutrient uptake.

3. Inert: LECA is an inert growing media, meaning it does not contain any nutrients that could interfere with plant growth or cause nutrient imbalances.

4. pH neutral: LECA has a neutral pH, which means it is suitable for a wide range of plants and can be easily adjusted if necessary.

5. Lightweight: LECA is very lightweight, which makes it easy to work with and transport, and also reduces the weight of potted plants.

6. Long-lasting: LECA is a durable material that can last for years with proper care, making it a cost-effective option for long-term plant growth.

Overall, LECA is a great option for plants that require good drainage and aeration. It can be used as a standalone growing media or mixed with other materials to create a custom soil blend.
