Aquponics is a new, innovative and eco-friendly way of 'growing your own' whilst creating your own eco-system. Clay pebb are a popular hydroponic medium around the world. Manufactured in Germany they are derived from a renewable and plentiful source (clay), it is considered an ecologically sustainable medium. The clay is formed into pellets and then fired in rotary kilns at 1200C. This causes the clay to expand inside, like popcorn and to become porous. Fishplant Clay pebbles are light in weight, do not compact and are completely reusable - they can be cleaned and sterilised after use. They are also inert, pH neutral and contain no nutrients. Because the pellets drain freely and don't hold excessive water, they provide good oxygen levels around the root zone.
