By not using soil, hydroponics irrigation methods in conjunction with a greenhouse can allow you to completely control your environment and grow more vegetables than using conventional techniques. For maximum production per square foot while using a minimum of moving parts, NFT hydroponics is the optimum way to grow leafy vegetables. It also allows you to grow them literally anywhere—from rooftops to deserts and all the way to very cold climates.
To grow leafy vegetables such as lettuce and herbs, the Nutrient Film Technique (N.F.T.) style of hydroponics is normally integrated into a greenhouse environment. It’s a closed system in which water, minerals and oxygen are re-circulated over the plant’s roots, eliminating evapo-transpiration and the unnecessary waste of precious resources. Because the plants get everything they need all the time ,the energy they would normally spend searching for minerals in the soil is used to grow bigger vegetables with NFT hydroponics. Basil, cilantro, parsley, brussel sprouts, arugula, watercress, fancy lettuce, head lettuce, bak choy and even mazuna will grow 20-30% faster using hydroponics, allowing you to turn crops more often than using conventional in-ground non-greenhouse farming. (Estimating approximately 20-26 turns annually)
Agra Tech works closely in conjunction with American Hydroponics, (AmHydro.com) a company that designs and manufactures manual systems that provide top returns on investments for growers from 60 feet to two acres.
Agra Tech also works with Hort Americas (hortamericas.com) that sells automatic systems that are ideal for two acres and more. Both companies are experts in hydroponics and know how to produce high-quality vegetables to make healthy profits.
