HYDROTON® expanded clay is a popular medium for both aquaponic and hydroponic gardening around the world. Manufactured by a German company, Oekotau Easy Green, the clay offers many advantages when compared to normal soil.
In aquaponic and hydroponic systems, soil is replaced by natural clay pebbles. It is derived from a renewable and plentiful source (clay) so 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 become porous.
Hydroton expanded clay pebbles are light in weight, do not compact, are completely reusable - they can be cleaned and sterilized 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 and are particularly suitable for aquaponic flood and drain systems and hydroponic systems. Notice how the roots in this cross-section go all the way down to the water level.
When you order Hydroton from aquaponics usa, you are ordering 8-16 mm Pellets in a 50 Litre Bag.
