There are three primary types of grow environments within an aquaponics system: NFT (nutrient film technique), float beds, and media beds. These grow environments have considerable differences in how plant roots obtain necessary water, nutrients, and oxygen. Furthermore, the growing medium provides the plant roots with an anchor point. A variety of grow media options are available that may provide better nutritional profiles, aeration, and/or water retention to facilitate seedling growth and improve nutritional yield.
