When someone asks, "what can be a green house", a plausible answer to the question needs to be that, "it is a purpose-built building or covered place, where plants are grown, more importantly regardless of the natural weather conditions". It can be as small as a little room so when large as being a whole complex and could be domestic too as commercial. Now, the fundamental principle on what the Green Houses work is, "allowing natural sunlight to plants and containment/ moderation of the heat, the sunlight carries along" this also purpose is achieved by constructing them transparent material, which in many in the cases is either plastic or glass. The temperature inside it can be controlled by creating small ventilators or through installing of air conditioner and heaters. Green houses may be extremely effective in aspects of extreme weather. Very hot regions like deserts are often unsuitable for growing crops. Similarly very cold regions like Siberia are also unsuitable for natural expansion of vegetation. Hence, certain food necessities are met this way. Speaking from the "Green House Design", there aren't strict limitations regarding size, shape and material in the proposed structure. Instead, the pliability allows someone to prepare a custom green house keeping in view one's own limitations, i.e. available land/ resources and targeted volume of plantation. For commercial purposes, These houses are built with glass structure, that are more dependable/ secure and so are built inside the model of large barracks. In advanced countries; they may be monitored electronically for better growth and maximum yield. Netherlands, as an example props up record for largest number of green houses inside a country exceeding 9000 of them. For domestic purposes, plastic is much more preferable being cheap and easily installable. With the advancement in agriculture industry, improvements in green house technology may also be seen. Historically, the green houses were initially built in order to save the crops from unexpected rain and hailstorms. Initial Designs were not transparent, instead were either made from hard fabric or metal sheets, however with the scientific development, it evolved in to a profitable business. Today's "Green house Design" encompasses following salient features: • It must at the very least be covering 50 meters of plain area. • It ought to a minimum of be 10 meters in length, 5 meters in width and 3 meters in height. • Foundation depth of the structure should be 0.5 meters, though the deeper the higher principle could be applied with this case. • Door in the green houses needs to be 1 ½ meters in height and 0.6 meters in width, whereas ventilating window ought to be 2 x 3 feet and really should be installed on the opposing wall of the door wall. • It will be constructed preferably in open areas, where sunlight is designed for greater degree of the day. • In areas, where there exists a risk of intrusion of wild birds or animals, the green house can be protected having a firm layer of metal grill. To summarize the discussion, following points need to become remembered while dealing with the phenomenon under question. • What is GH: A structure, built to provide artificial environment for plants to grow under unfavorable outer conditions. They are designed to raise vegetation and grow unseasonal plants and fruits. • What are the key benefits: o Off-season crops regardless of type might be grown o Higher yield can be achieved through provision of most suitable environment o Requires less utilization of chemical fertilization and water irrigation, thus minimizing expense of yield.
