How does it work

The fish tank produces nutrient-rich water that is piped through the grow beds, fertilizing the crops and eliminating the need for costly pesticides, herbicides or fungicides.

The water is filtered through the gravel in the grow beds and returned to the fish tank, where the cycle continues. The system can be equipped for rainwater harvesting and with solar panels to further reduce costs and energy consumption.

Note to the Budding Farmer: A single low-maintenance tank and grow-bed system can meet the nutritional needs of a family of four, with enough excess to sell to generate household income. Modular units may be added to expand the system as funding allows.
