Aquaponically-grown Pea Shoots are the perfect topper to a fresh farm salad, or go well with a stir fry, on a sandwich, or in a veggie wrap…the uses are endless! Grown using organic practices grown by our newest local veggie grower – Fort Orchard Aquaponics (Gold Beach). And like the name implies, the pea shoots are grown with organic methods in a closed-loop, aquaponics greenhouse!
So what is Aquaponics? Simply put, it is a system whereby plants grow in water instead of soil, using the waste that fish produce to create the nutrients that the plants need.
An aquaponics system works by creating a nitrogen cycle. In this cycle, the three main elements, the fish, the plants, and the bacteria, share the water. In the fish tank, fish produced high ammonia wastes. The pump carries this waste into the growing tubs, where the bacteria convert these wastes into nitrites and then into nitrates. Those nutrients then flow under the “rafts” to be taken up by the roots on the plants.
These nitrates become food for the plants to grow, and in return, the plant roots clean the water in the growing tubs before it returns to the fish tank for the fish to live. It’s a continuous cycle, where the bacteria convert fish wastes into food for the plants, and the plants clean the water for the fish.
