History of Hidropolik 1. Babylon, China, Egypt and the hydroponic technique has been used since the period of the 16th AD. Depending Parks Babylon (The Hanging Garden of Babylon) is believed to have used this as a kaedah hydroponic crops, then followed by the last days Aztez tribe in Mexico (where the Indian community is a floating plant in the shallow Sea of surface or can be said as a raft system). Marco Polo in his wanderings noted that there are people in the country who grow hydroponic China. In the end of the reign of Egypt also contained hydroponic planting activity. 2. Britain In 1699, Woodward, British scientist, has been running the plant studies using water as the medium, through roses restaurant supply which mineral salts dissolved roses restaurant supply in water and added a little ground. As a result, the principal crops grown in soil that is mixed well and has not diminished. De Saussure (1804) is said to be more significant for the embryo of research that uses hydroponic nutrient solution as the initial composition of the various components of mineral elements in the distilled water. In the early '70s, British scientist, Dr. Allen Cooper, has successfully introduced the technique of Nutrient Film Technique (NFT), which is the best hydroponics system. In this technique, a solution of mineral salts from the tank flows into the roots of hydroponic plants in a trough, then the solution is returned to the original tank. This technique has grown in line with the development of digital technology that can be operated through a computer system. 3. U.S. In the 1930s, precisely in 1933, American scientists, WF Gewricke, from California Agriculture Research Center, University of California, the United States roses restaurant supply has been commercially introduced this rule. Since then, the hydroponic system was developed and is packed with a variety of techniques typical for commercial purposes. Gewricke also managed to grow hydroponic tomatoes. Tomatoes that grow up to 7.5 meters. Greenhouse technology developments in western countries also have fostered because hydroponic greenhouse hydroponics farming activities can be run throughout the year. Furthermore, hydroponic growing systems to the commercial direction. Patented invention then it started to encourage people to develop a number of commercial units. At least, recorded hydroponics area to 0.8 hectares (ha). Unfortunately, the effort proved uneconomical. The development of hydroponic roses restaurant supply shows bright spots again after World War 2. For the vegetable needs of the soldiers, the United roses restaurant supply States (U.S.) to build a hydroponic unit in some islands roses restaurant supply of the Atlantic Ocean and the Pacific. One of them is located in Chofu Japan. On an area of 22 ha, the cultivated hydroponic cultivation. Media used in the form of fine gravel, while the supply of nutrients in the form of chemical fertilizers streamed directly to each plant. In this way, the supply of fresh vegetables to the kitchen U.S. troops remain continuous and do not have far to import roses restaurant supply from U.S.. 4. Development Canada hydroponic roses restaurant supply unit, which is really a matter of economic consideration, there was the mid-1960s. A greenhouse industry is located in British Columbia, Canada was forced to switch to hydroponic cultivation. Because, planting tomatoes dominated the ruined because of diseases carried by land. To remain safe, they should be "put out" the plant from the soil and replace it to the hydroponic system. Tomatoes are then planted in containers filled with sand and nutrients are channeled through the hatch. In that decade, the attention of people towards hydroponic intensified. Research and studies even more incentive. Rapidity was driven again by the oil crisis in Europe (1970). Because of the scarcity of oil, the cost of heating in the greenhouse industry roses restaurant supply swells. The planters and researchers are forced to set aside more funds for the cost of this one. One way to avoid losses to be borne is the optimization of the harvest. Finally, they chose hydroponic cultivation to achieve that goal. 5. Netherlands In the decade of the 1980s was critical for hydroponic farm. It started when Dutch researchers found levels of methyl bromide in the water dangerous ground. Ironically, the content of which is sourced from the soil sterilizer has been scattered in various areas. The Dutch government immediately banned the drug is sterile. The impact of the ban makes the pe
