Hydroponics can be a means of growing plants in nutrient water without the use of soil. Instead of soil a non-reacting medium is used such as perlite, gravel, or even the husk of coconuts. It was generally known as early as the 18 century that plants absorb their minerals in water as ions. The soil in traditional growing provides for a nutrient reservoir but will not actually contribute to plants growth. Water dissolves the minerals in the plants soil enabling the plants for their services. In hydroponics the minerals required for plants growth are artificially dissolved within the water making soil unnecessary. You'll be able to grow almost any soil based plant using hydroponics. Hydroponics is unquestionably a promising field that there are much research into various ways in the academic community.
The first book ever published on hydroponics was published in 1627. After which it, water cultivation soon became a popular technique. Experiments were done along with 1699 it was found that plants grown in sterilized water grew less rapidly then plants grown in plain water. This can be due to the dissolved ions throughout non-pure water. By 1842 scientists had published a directory of nine elements considered to be responsible for plant growth and the results of which resulted in what is known as modern hydroponics. At first they used soilless cultivation and grew terrestrial plants with all the nine essential elements. It quickly spread throughout academia and became an area of hot research.
One of the primary achievements of hydroponics was performed by Dr. Gericke at the University of Berkley. He were able to create tomato plants that grew to around 25 feet tall. Back then this was considered only possible due to the usage of hydroponics. He claimed that hydroponics would revolutionize growing. If perhaps he were alive right now to see how it has. He wrote the sunday paper in 1940 called the Complete Help guide to Soilless Growing which took over as the go to guide on hydroponics of the day; although, in the beginning he refused to publicly reveal his secret.
Due to the extravagant nature of his claims several scientists go about reviewing his work. At first they found that soilless growing wasn't any better than soil growing. They found out that the yield of crops were limited by other factors other than minerals, like light. The research overlooked many of the important factors that make hydroponics benefit plants. Namely that hydroponics allows the plants roots to get more oxygen. During this time period mineral solutions were developed called Hoagland solutions were developed and still in use today. Hydroponics was applied on Wake Island ahead of time to grow vegetables its keep was no soil. Recently hydroponics has become thoroughly researched by NASA.
With the advancement of modern hydroponics along came advances in grow lights. In the beginning the introduction of HPS (high pressure sodium) grow lights allowed plants to become grown indoors. They produced high light output and allowed plants to mature fully. Recently the advances of LED grow lights initiated a policy of to revolutionize the joy of hydroponics. They completely eliminate the heat issues that occur with HPS lights and can reduce electrical costs by as much as two thirds.
