We grow many types of lettuce in a 3500 sq ft passive solar designed greenhouse using Aquaponics. Because fish are our fertilizer “engine” we can use no chemicals, pesticides or fertilizers even if they are organically approved. This makes the produce very fresh and natural with a longer shelf life. We use Tilapia and Koi, but will eventually use only Tilapia because of its sustainability. We use only 2% of the water normally required to produce the plants in the system and less than 3% of the energy required to grow it conventionally. Our greenhouse at full capacity will have almost 13,000 plants growing at the same time as well as another 8,000 seedlings all on a footprint of 1/12 an acre.
