Aquaponics Grow Bed (Updated 2020)
An aquaponics grow bed is one of the 3 main components in any aquaponics system, the other two being the fish tank and the water transfer system. The grow bed is often an aquaponics biofilter itself in that, the natural bacteria takes up residence on the surfaces of the gravel media. This makes it a self contained ecosystem of bacteria processing ammonia from the fish, and converting it to nitrates that become nutrients for the plants. As a grower, you will find that this is one of the most important benefits of Aquaponics.
