Clay Balls are baked clay pellets that form an ideal substrate for use by beginners to experienced growers. Their unique structure makes the clay balls the ideal basis for growers who want to control the application of nutrients and the humidity level of their plants throughout the entire process of cultivation in a simple way. Clay Balls are manufactured from special types of clay that have a low soluble salt content. Because of this, they are particularly suited for use in hydroponic and aquaponic systems.
Clay Pebbles have both high porosity and high air content which stimulate the development of strong roots that grip the substrate well. Clay Pebbles are inorganic, have a neutral pH value, are fungus free and do not rot. Clay Pebbles consist of different components that together form an optimum, heterogeneous structure that is ideal for root development.
Clay Pebbles are also known as "Hydroton", "LECA" (Light Expanded Clay Aggregate), or "Clay Pellets". They are extremely easy to use, and comfortable to garden with, leaving no residue and no dirty hands.
