At Chico State, which is developing its own aquaponics program, excrement from koi and bass provides the nutrients for the plants, which are housed in a greenhouse. Fish effluent is transformed into a nutrient for plants, then recycled back into the fish tank. Although it uses significantly less water than comparable field crops, it makes having a bacteria-free environment imperative.Īquaponics: A combination of hydroponic growing and fish (or sometimes other creatures, such as snails). Aeroponic production does not involve a growing medium instead, roots dangle in the open air and are misted with nutrient-rich water. As with aeroponics and aquaponics, the hydroponic plants need nutrients and can be grown in vertical racks or on your kitchen counter.Īeroponics: This method does, indeed, put the air to work. Hydroponic farms do not use soil but do have a growing medium, such as coco coir, or coconut fiber, the material you often see as the exterior layer in open-basket hanging pots. Hydroponics: The “hydro,” or “water,” is key to growing in this form.
There are three growing methods that end with “-ponics” (from Greek meaning “to labor” or “to work”):
