Canna Aqua Clay Balls / Hydroton

Canna 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. Canna Aqua 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.

Canna Aqua Clay Pebbles have both high porosity and high air content which stimulate the development of strong roots that grip the substrate well. Canna Aqua Clay Pebbles are inorganic, have a neutral pH value, are fungus free and do not rot. Canna Aqua Clay Pebbles consist of different components that together form an optimum, heterogeneous structure that is ideal for root development.

Canna Aqua 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.

Do Canna Aqua Clay Pebbles Float?

Canna Aqua Clay Pebbles are the best sinking clay pebbles we have come across. If you are using them for Aquaponics, some will float if you fill the grow bed with water to the level of the clay pebbles. Aquaponics works best in flood and drain when the water fills only to within 2.5cm of the top of the clay balls, so that sunlight doesn't create a green layer of algae on the clay pebbles.

When washing the clay pebbles, you will notice that up to 50% of these balls float to begin with, but within a few days all will sink. This is much faster than other clay balls we have tested!
