This is a Modular Aquaponics System for growing vegetables at home with your fish tank pump supplying nutrients to the plants. The system is infinitely stackable and can be arranged in many ways to make an interesting aesthetic.
The cans are all easily removed to work as individual pots. The system will be easily customizable for individual plant setups as each tin can be filled with different planting media. Best of all the water once its passed through the system becomes totally clean and fresh for the fish.
