How Does It Work?

Fish Tanks

Firstly, fish are placed within tanks. As time goes by, they dirty the water with their waste and then this water is pumped out of the tanks and into the growing beds. In our farm, we will use tilapia, a highly versatile species that can live comfortably in a wide range of conditions. 

Growing Medium

The water is then slowly released into the growing medium: a bed of gravel in which bacteria can convert the fish-waste into chemicals that are useful for plants. Using a growing bed means we are not dependent on having fertile soil to make this farm work, meaning we can keep the farm in one place indefinitely.

Raising Crops

Finally, plants remove the broken-down fish waste, which allows them to grow more quickly than would otherwise be possible, and simultaneously returns clean water back to the fish tanks.
