A greenhouse is basically a structure wherein transparent material like glass is used in walls and roofs. Such a structure is made this way in order to provide specific climatic conditions to certain plants that require it.
The size of the structures is not as relevant as it could be a small shed. It could also be the size of a large industrial building.
It’s also called a glasshouse. If there is adequate heating, it is also referred to as hothouse. A smaller greenhouse is at times referred to as Cold Frame.
Why greenhouses matter so much is that the inside of a greenhouse can get quite warm due to exposure to direct sunlight which can protect the plants from cold weather.
Commercialization of greenhouses has also happened over a period of time. It’s possible to spot a lot of commercial greenhouses now. These commercial greenhouses now serve as advanced production facility for growing flowers or vegetables.
In order to ensure climate control inside greenhouses, a lot of high tech tools are leveraged now. To make sure that plant growth happens properly, greenhouses contain advanced equipments for heating or cooling as the case may be. There are equipments for screening installations as well. At times, computers are in place to control and monitor the functioning and use of these advanced tech tools and processes.
To assess the state of the micro-climate comprising air temperature, vapour pressure deficit, relative humidity etc., a variety of techniques are utilized. The reason for the evaluation of this sort is to minimize the risk related to the production before a particular crop is grown.
Ventilation forms an important part of greenhouses. It provides fresh air necessary for photosynthesis and respiration of the plant. It can control the humidity and temperature of the greenhouse and provide measures of climate control.
When it comes to climate control, heating plays an important role. Providing heating to a building which has solid walls requires less electricity as against a greenhouse. A lot of transparent material is used to allow light inside the greenhouse and hence, the effect of heating is diminished. Climate control in a greenhouse can be challenging with respect to heating.
Cooling is relatively easier. When heating exceeds its limits, windows can be opened to cool air. It can be done manually as well through electronic controllers. Electronic controllers can keep an eye on the temperature and tweak the furnace accordingly. It could be quite simple like a thermostat. However, it could get tricky when it comes to managing bigger greenhouses.
Managing a greenhouse can be a challenging exercise. Climate control inside a greenhouse is an even more daunting task. Thanks to the advanced technologies in the recent years, a lot of automation has been possible in terms of climate control inside greenhouses.
Climate control using these advanced tools has become quite crucial because it is otherwise difficult to prevent diseases. It can affect the plant growth too. So automation has helped the cause of climate control inside greenhouses a great deal. Research is still on regarding how to refine the climate control process further in order to arrest the climatic conditions at the point of origin.
