Meet the Aquafarm: an awesome fish tank that cleans itself and grows your food. You just have to fill it with water, add your fish, and plant some seeds. Your plants clean the water and the fish feeds the plant with its poo and pee. The Aquafarm uses 90% less water than traditional forms of farming. This fish tank is easy to set up and looks quite decent too.
The Aquafarm ships with everything you need to get started, including seeds and fish food. You can’t grow just anything using this system, but the idea is quite clever.
