==== ==== Discover How To Easily Build An Attractive And Affordable Greenhouse That Will Grow Anything In Any Conditions... http://tiny.cc/greenhouseplans ==== ==== Harvesting From the Water Conventional farming makes people plant crops over a field of land, give it water to help it grow then harvest it when the time comes. This was practiced for many years until the demand for food increased which made scientists rely on other techniques to increase production. Such practices made the use of pesticides and herbicides, fertilizers, contaminated sewage sludge and irradiation. Since these methods are harmful to the health, people have gone back to organic farming that does not use any of these methods. Technology has found another way to increase crop production without jeopardizing the health of people and the environment. This can be done by hydroponics farming. Plants need water to survive but this is only one ingredient. The other and most important are the nutrients. Scientists have discovered that it is only when this is diffused into the water system that the roots of the crops consume it making it grow. By doing this in a controlled environment such as a greenhouse, the nutrients can already be mixed into the water system allowing the crops produce more yields which is what hydroponics gardening is all about. To prove how effective it is, scientists made a comparative study on the growth of tomatoes. One batch used soil and was able to produce ten tons. The other batch used hydroponics and was able to produce 60 tons. This shows that this method can produce 6 times more than traditional farming. Almost any type of plant that is grown using this manner will product high yields. Though some crops will be able to produce more than others, the length of time to harvest it is still faster than the old method which gives a faster turn around for farmers. The farmer does not have to check and pull out weeds, till the land or look for diseases that normally happen during soil cultivation since there are none. Some people might think that this will consume a lot of water but it doesnt since it is reused which also consumers less than traditional farming. The problem with a controlled environment is that the plants may not be able to get the proper sunlight and carbon dioxide that to help it grow. This problem can be addressed by installing lights and infusing artificial CO2 into the air. There are other ways to cultivate crops while inside a green house. One method is called deep
