Aquaponics and Hydroponics

Hydroponics is the method of growing plants in mineral nutrient solutions. While most often grown in water, this soilless technique can also be used with inert mediums such as perlite or gravel. Aquaponics is very similar, but it incorporates raising fish for food into the system. The fish supply nutrient rich water to the plants, which are being grown hydroponically. When the fish reach a certain size, they are harvested as well.
