The term Aquaponic refers to a soil-free way to cultivate plants that incorporates the use of fish. Aquaponics combines hydroponics in a controlled environment that creates a balanced ecosystem that benefits crops as well as the fish.
Many people are turning to Aquaponics to grow herbs and vegetables inside their homes for several reasons. With these systems used indoors, it almost completely eliminates the insect problems faces with outdoor gardens. These systems are also perfect for those who do not have much land to utilize for gardening.
