Product details LECA (Lightweight Expanded Clay Aggregate) Hydro stone balls are a type of soil-less growing medium that is commonly used in hydroponic and aquaponic systems. They are also popular for growing plants in containers, especially for those that require good drainage. LECA balls are made from clay that is fired at high temperatures to create a lightweight, porous material with a honeycomb-like structure. They are inert and do not contain any nutrients, but they can hold water and provide aeration to plant roots. To use LECA balls for plants, you can fill a container with them and then plant directly into them. Alternatively, you can use them as a layer in the bottom of a container to improve drainage. They can also be used in hydroponic systems by suspending the plant roots in a container filled with LECA balls and then periodically flooding the container with nutrient solution.
