Plants do not need soil as such: they need only nutrients and moisture contained in the soil, and these could be supplied through gravel that contains water. Hypodronics is not a new process. As long as the 1960 an english physician tried gro- wing plants in woter in a labolatery experiment and in the 1800 s German researchers used the method to develop many of the formulas for plants nutrient solution still in use today. About a generation ago hypodronics moved out of the research lab into commercial use. With reinforced plastic film.The plants are fed by inorganic nutrients dissolved in water Wich is supplied by a plastic pipeline. The feeding and watering system is automated. Tem- perature, humidity and air circulation are carfully controlled. Air conditioning and hearting equipment keep the temperature at 29 degrees celsius by day 18 degrees by nigt. No entry is given to wind, weeds, or insects. In recent years hypodronic farming has been expanding to many parts of the world par- ticularly in areas where water is in short supply and temperatures are too extreme for ordin- ary agriculture.A hypodronic farm operated by the government of kuwait produces fresh tom- atoes at a desert sit near the capital city.At puero penasco, and on sadiyat island in abu dhabi experimental hypodronic farms use seawater that is desalted by special installation on the coast.
