Greenhouse Design

Green house is a building that has a skeleton or shape bubble, then wrapped with a clear material and sun shine. This will be able to pass sunlight to the plant to the maximum that serves to protect the plant from extreme climatic conditions and may damage the plant. Green house or green house is very important in supporting agricultural productivity because in the green house there are controlled environmental conditions ranging from sunlight / light, humidity, temperature and the amount of irrigation. With controlled environmental factors, crop yields are expected to increase. When the ancient times when people make green house by making greenhouse but because of the expensive materials and tools used so now people prefer to use plastic to make it with a variety of designs and shapes. The cultivation of plants within the greenhouse has the advantage of a more controlled microclimate and uniformity of production in each plant. In contrast to the function of greenhouses in subtropical climate areas that are used to control the microenvironment, the presence of greenhouses in the tropics is more likely to crop protection. Greenhouses in the tropics are used to protect crops from pest attacks and retain rainwater that falls directly into plants that can damage crops. Therefore, the design of greenhouse design in the tropics is simpler than in subtropics. The temperature inside the greenhouse becomes higher than the temperature outside the greenhouse due to the change in incoming solar radiation (short waves) that heat the surface in the greenhouse and then the surface in the greenhouse re-emits in the form of long waves.
