This Fair Companies interview is fantastic. They visit Rik Kretzinger and get a great tour of his revolutionary garden design. He has managed to create an inexpensive, highly efficient and configurable aquaponics system that is controlled by an Arduino .
This large scale Aquaponic system is designed from the A-Frame Deep Water Culture Column (ADWCC) Prototype designed by Nelson Mmbando, 256 square feet foot print capable of producing approximately 400 heads of lettuce every two weeks. This system also incorporates vermiculture to break down food waste and introduces the nutrients back into the system.
Nelson utilizes the concepts he fine tuned during his thesis project and is a great example of a well thought out aquaponics system the expands the standard model into vermiculture.
