In today’s world wherever you go the slogans depicted here and there is, go the green way, save tree save future and so on. The most popular phrase that everyone would have experienced is, “you aren’t the last human being to survive in this world”. This clearly sets out the message to save the future. So as an early wake up call, preparations for the future have to be made. Greenhouses have come at right time, which can be implemented in the future even if there is no space available to cultivate the plants.
Greenhouse concept:
What is this greenhouse concept? Greenhouse is nothing but kind of a house wherein plants can be cultivated. What makes it very special is that we can set a greenhouse in a place whichever is suitable for growing plants. Greenhouse is not a house, which is built by means of cement bricks etc. Greenhouse is a house, which is built using either by glass sheets or plastic sheets that are transparent. Glass sheets used are well-defined ones where as the plastic sheets are usually made of polyethylene or PMMR’S. Plastic sheets are strong and stiff longitudinally but not as strong as in transverse direction. So this paves the way for glass sheets as a common material to be employed in making of greenhouses. The small greenhouses uk made out of glass sheets are also known as glasshouses. Glasshouses can be interconnected to a computer and optimal parameters can be maintained so as to help the growth of plants. Greenhouses can be classified into two types: large greenhouse and small greenhouse. Small greenhouses are the common sight in United Kingdom. One can notice as many number of greenhouses if he turns out to a trip to United Kingdom. The very fact, which makes it most popular, is the space constraint, attracting as many no of people to own it. Greenhouses are used widely in UK for the cultivation of decorative flowers, vegetables and so on. Small greenhouses are employed by small farmers to gain more money from. Many ask what is the advantage of a greenhouse? The advantage of growing plants in a greenhouse is that crops can be cultivated in all climatic conditions thereby we can have an edge over the others who conventionally grow the plants. Based on the weather the conditions the greenhouse can be modified perfectly so as to help the plants to get the nutrients in a balanced proportion. Hence small greenhouse has attracted many in UK.
In winter season the climate other than the equatorial and temperate regions are very severe that growing vegetables are almost impossible in that temperature. For this it reasons all the houses situated in that region have a greenhouse adjacent to their house. Greenhouse is a small building where the temperature is made to be higher than the surroundings and it is used to cultivate the plants.
Principle of Working
In ordinary greenhouse the heating element is the sun where the temperature is increased in the greenhouse by trapping the sunlight inside the greenhouse. This is done with the help of inclined glass rooftops in the greenhouse. As the glass sheets are inclined they make the heat rays to go into them and when they return to them after reflecting they come and fall on the glass due to total internal reflection the heat rays are reflected a no of times thus by causing the increased temperature in the greenhouse. In the case of climate controllers provided it is capable of providing a temperature of 70 degree Celsius when the outside temperature is as low as 0 degrees. This is only done by the best internal design of the greenhouse.
Quality and Quantity
In considering the production rate and quality of the vegetables grown in the greenhouse with the vegetables that are grown in the field, the vegetables that are grown in the greenhouse are as good as the ones that are grown in the field. To say the truth the greenhouse vegetables are better then those vegetables that are grown in the field due to the reason that they are grown in a controlled environment where as there counter parts are prone to drastic temperature variations. The production rate in the greenhouse is larger than the field because the wastage is minimal in the case of greenhouse where as the field there is a equal chance weeds getting grown along with a higher probability of attack from the pests.
Cost Involved
The cost involved in growing the vegetables in the greenhouse is slightly higher than the field. But the quality of the vegetables got is high and even. This make the manufactures to incur with the greenhouse cost excess.
The vegetable growth in the greenhouse is accompanied with its own pros and cons. The principle involved in the greenhouse is controlled environment in addition with trapping of sunlight. The production rate and the quality associated with the vegetables in the greenhouse are high compared to their counter parts. Though the cost involved is high it is bearable.
