Mediamatic.net - Aquaponics Mediamatic - The Aquaponic-system is a way to sustainably produce food in the city, because it hardly takes up any space. Plants & fish are cultivated together. The fish poo feeds the plants, & the plants clean the water for the fish. There's hardly any waste. In addition to this, Mediamatic has now developed Miniponics, the same system on a micro scale, which can be built and kept in offices, classrooms, living rooms, & even on balconies.
