Growing Media

The growing media in aquaponics system is dominated by clay pebbles, as they are perfect for the root structure and to maxmises surface area available for beneficial bacteria. Clay pebbles are also known as clay balls, or Light Expanded Clay Aggregate (LECA). Often perlite is used in growing channels in aquaponics systems (inside net pots) as it is a cheaper media. Growstone is a recent addition to the media which can be used in Aquaponics, and is made in the United States from recycled glass.
