Urban farming techniques like hydroponics, aeroponics, aquaponics, roof gardening, and kitchen gardening allow for food to be grown in controlled environments within cities. Hydroponics grows plants without soil by using mineral nutrient solutions, while aeroponics uses no growing medium and sprays plant roots with nutrient mists. Aquaponics combines aquaculture and hydroponics by using fish waste as natural fertilizer for plants. Roof gardens and kitchen gardens make use of small urban spaces like rooftops and around homes to grow food. These controlled environment agriculture methods provide food and environmental benefits for urban areas.

CONTROLLED ENVIRONMENT AGRICULTURE CEA HYDROPONICS,  AEROPONICS, AQUAPONICS ROOF GARDENING KITCHEN GARDENING
HYDROPONICS, AEROPONICS, AQUAPONICS
HYDROPONICS The word, Hydroponic, comes from Latin and hydro" means "water" and "ponos" means "labor". Simply put, it is the art of growing plants without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite or gravel.
TYPES OF HYDROPONIC SYSTEMS Drip System Ebb- Flow (Flood & Drain) Nutrient Film Technique (N.F.T. ) Deep Water Culture Wick System
HYDROPONICS SYSTEM Drip Irrigation – System in which water and nutrients are delivered via gravity dripping your H2O supply at a constant rate. Ebb and Flow – An inert medium that the plants grow through is flooded periodically.
HYDROPONICS SYSTEM COTN..  Nutrient Film Technique(NFT) – A shallow stream of water is recirculated through the plants roots.  Deep Water Culture (DWC) – A plant suspended in water that is constantly being aerated.  Wick System – Utilizing capillary action to deliver water to the plants
AEROPONICS  Aeroponics is a great alternative for growing plants in small spaces, especially indoors. Aeroponics is similar to hydroponics, as neither method uses soil to grow plants; however, with hydroponics, water is used as a growing medium. In aeroponics, no growing medium is used.
HOW DOES AEROPONICS WORK?  In a typical aeroponic system, plants are usually suspended on top of a reservoir, within a tightly sealed container. A pump and sprinkler system creates vapors out of a nutrient rich solution, and sprays the result in the reservoir, engulfing the dangling plant roots. Plants are inserted into the platform top holes and supported with collars.
TYPES  Low-pressure units  In most low-pressure aeroponic gardens, the plant roots are suspended above a reservoir of nutrient solution or inside a channel connected to a reservoir. A low-pressure pump delivers nutrient solution via jets or by ultrasonic transducers, which then drips or drains back into the reservoir.  High-pressure devices  High-pressure aeroponic techniques, where the mist is generated by high-pressure pump(s), are typically used in the cultivation of high value crops and plant specimens that can offset the high setup costs associated with this method of horticulture.  Commercial systems  Commercial aeroponic systems comprise high-pressure device hardware and biological systems. The biological systems matrix includes enhancements for extended plant life and crop maturation.
ADVANTAGE  Water and nutrient used efficiently  Less need for nutrients and water than traditional hydroponics systems  no need to worry about weeding  takes up very little space  It uses considerably less energy and water than traditional agriculture.  Reduced risk of disease and pest infestation in a controlled environment
AQUAPONICS  Aquaponics is the improved combination of aquaculture and hydroponics. It involves capitalizing on the benefits of each system and eliminating their drawbacks. There are three main elements to the aquaponics system: the fish, the plants, and the nitrifying bacteria of the worms and microbes. The fish produce the waste which microbes and worms turn into fertilizing agent as organic food source for plants. The plants, in turn, provide the natural water 'filtering agent' for the fish to thrive.
PARTS A MINI AQUAPONIC SYSTEM A tank for the fish Gravel for tank bottom Water pump and tubing Air pump, air stone and tubing Fish and plants
ADVANTAGE  If you chose it aquaponics provide food at its maximum, food from plants as well as the fish.  Water used efficiently for plants and fish  Plants grow much faster since roots are constantly fed nutrients .  No need for artificial fertilizers  no need to worry about weeding  it's a complete natural and organic system
NOT NEW!?!?!?!?!?!?!? Hydroponic gardening has its roots in ancient history. 600 B.C., gardeners at the Hanging Gardens of Babylon–one of the seven wonders of the world–may have employed hydroponic principles.
ROOF GARENING  A roof garden is a garden on the roof of a building. Besides the decorative benefit, roof plantings may provide food, temperature control, hydrological benefits, architectural enhancement, habitats or corridors for wildlife, recreational opportunities, and in large scale it may even have ecological benefits
KITCHEN GARDENING  The traditional kitchen garden, also known as a potager is a space separate from the rest of the residential garden – the ornamental plants and lawn areas. Most vegetable gardens are still miniature versions of old family farm plots, but the kitchen garden is different not only in its history, but also its design.
