Hydroponics - The Way of the Future 96%

Hydroponics The Way of the Future Woodstock 1      Hydroponics: The Way of the Future    The term hydroponics is considered by many, in this day and age, as a way of growing  marijuana. Hydroponics, however, is not just used for growing marijuana, but can be used to  grow and produce salad greens, lettuces and culinary herbs. In fact, hydroponics is a relatively  new term for growing plants without the use of soil. In the book ​ Hyrdoponics: The Complete  Guide to Gardening Without Soil ​ by Dudley Harris, he says the term hydroponics is derived from  two Greek words “hydro” meaning water and “ponos” meaning “labour.”  Howard M. Resh the  writer of  ​ Hydroponic Food Production​  points out, “The hanging gardens of Babylon, the  floating gardens of the Aztecs of Mexico, and those of the Chinese were a form of “hydroponic  culture” (1). This shows that even though the term is new, the practice of hydroponics has been  in use for hundreds of years. Resh’s book also tells us that the term itself was coined by W.F.  Gericke of the University of California after he started using non­soil farming on a commercial  scale for his experiments (2). Resh helps us clearly define what hydroponics is:  Hydroponics can be defined as the science of growing plants without the use of soil, but  by the use of an inert medium, such as gravel, sand, peat, Vermiculite, pumice, perlite,  coco coir, sawdust, rice hulls, or other such substrates, to which is added a nutrient  solution containing all the essential elements needed by a plant for its normal growth and  development (2).    Glenn Collins, a journalist for the New York Times, interviewed Dr. Giacomell​ i, a hydroponic  designer who is a professor of agricultural engineering at the University of Arizona ​ said ​ that  hydroponics done on a commercial scale with large greenhouses, special lighting, and takes quite  Woodstock 2  a bit of technical sophistication. Many modern hydroponic farms use rooftop weather stations to  monitor wind, rain, temperature, humidity, carbon dioxide and light intensity. There are also  irrigation pumps, greenhouse vents, exhaust fans, gable shutters and shade curtains (Collins).   With the use of hydroponics, societies can produce more food with less impact on  natural resources, thus helping preserve the land. However, the quality, and start up costs of  hydroponic food have become a subject of controversy. Despite some objections,
