Aquaponic gardens are closed loop systems that combines aquaculture (fish farming) and hydroponics (growing plants using water rather than soil). The fish in the water produces waste (ammonia), which is converted by nitrifying bacteria into nitrates, which fertilizes the plants. 'Filtered' water is then returned to the fish tank. The water is circulated through he system so there is no need to water the plants. You only need to feed the fish. The modular system allows you to stack as many tubes of either fish or plants that are needed and the solar panels provides the electricity to power the pump.
