If you are interested in hydroponics, you'll want to see "How To Make An Aquaponics System," a way of growing that is gaining in popularity. This is great way of growing plants which are fed by nutrients from the fish.
This youtube site is an online television series that celebrates food, where it comes from and the people who create it. Some of the videos you will see on this site include designing a sustainable aquaponics system, why eating trash fish is good for eaters, fishermen and ocean fish, growing backyard mushrooms, raising backyard chickens, winter greenhouse farming, visit to a rare wasabi farm, lambing season on the farm, a mom teaches her children the importance of food, urban gleaners reducing food waste to reduce hunger, cherry orchards in full bloom, a small scale integrated livestock farm, a love a good farmhouse food, an artists life on a small family farm, supa fresh youth farm helping underserved teens learn life skills, harvesting salt from the ocean, food wisdoms, the future of small family farms, the pleasures of eating home cooked meals, one farmers perspective on the raw milk debate, considering the true costs of raising pigs, rethinking the problem of food waste, a successful cherry farmer's toughest challenge, teaching kids hands on learning in the kitchen and on the farm, the world of artisanal salt according to Mark Bitterman, selling micro greens chef to chef and more. Aquaponics is all about growing fish and vegetables in an attractive, productive, integrated system, right in your own backyard.
Aquaponics is any system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In regular aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. When growing in an aquaponic system, the water from an aquaculture system is fed to a hydroponic system where the by products are broken down by nitrification bacteria into nitrates and nitrites, which are utilized by the plants as nutrients, and the water is then recirculated back to the aquaculture system. As existing hydroponic and aquaculture farming techniques form the basis for all aquaponics systems, the size, complexity, and types of foods grown in an aquaponics system can vary as much as any system found in either distinct farming discipline. The plants are grown as in hydroponics systems, with their roots immersed in the nutrient-rich effluent water. This enables them to filter out the ammonia that is toxic to the aquatic animals, or its metabolites. After the water has passed through the hydroponic subsystem, it is cleaned and oxygenated, and can return to the aquaculture vessels.
