Hydroponics...


Hello Everybody!! Today I´m going to talk about about Hydroponics. Later we will see what does this mean. These days I´ve been trying to make my own Hydroponic Cultivation and I think I´m doing well. Next time I´ll tell you how´s going mine and its results...

Hydroponics (from the Greek words hydro water and ponos labor) is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, or mineral wool.

Researchers discovered in the 19th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant's water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics. Hydroponics is also a standard technique in biology research and teaching.

The largest commercial hydroponics facility in the world is Eurofresh Farms in Willcox, Arizona, which sold 125 million pounds of tomatoes in 2005) under glass and represents about a third of the commercial hydroponic greenhouse area in the U.S.Eurofresh does not consider its tomatoes organic, but they are pesticide-free. They are grown in rockwool using the run to waste technique.
