This is an “Aqua Garden” I constructed for under $200. This modular system was designed to produce up to 80 heads of lettuce every 30 days via a small 400 gallon Koi pond.
I had so much fun building this system. I can remember learning about biology in science class growing up, fascinated with the complexity of life. Whenever I would pass a stream or a river, I would always stop to watch the creatures in the water. Building these systems are my idea of “Liberty” and the “Pursuit of Happiness”. We can do whatever we want once we break our own programming.
