This is a process or system by which plants are grown in a controlled environment. It is a structure mostly buildup of glass. The size of greenhouses may vary from small huts to huge buildings. A greenhouse may include high tech equipment such as sensors, pressure pad, heater, cooler etc. These customary greenhouse structures frequently comprise of straightforward glass or poly sheets shaping a rooftop and structure to encase a developing territory and have a radiator to give heat in the cooler months. There are two types of green house. They are glass greenhouse and plastic greenhouse. Greenhouse system can be used to control the different conditions needed for the better growth of plants. Greenhouse system can be used to grow a kind of plant throughout the year by providing the proper environmental conditions. Irrigation system is required inside a greenhouse. Sprinklers are used to water plants in a greenhouse system. Too much rise in temperature is controlled in a greenhouse by coolers or other system. Sensors can be used inside a egreenhous.
There are several kind of sensors such as temperature sensor, humidity sensor, pressure sensor etc. Temperature sensors can be used to automatically maintain the temperature inside a greenhouse system. The sensors are connected to a computer and a certain value is imputed, and if the data cross that limit then an alarm is switched on or other commanded actions are taken. For example, during a cold day the sensors are used and a certain temperature is noted as the boundary temperature. So, now is the temperature falls below it the alarm may be turned on or the heaters may be turned on automatically and then again if the temperature rises up to a certain temperature then it automatically is switched off. Ventilation is an important part of greenhouse. Without proper ventilation there may be problems with the plants. This makes sure that the air is flowing well around the greenhouse and temperature and humidity is maintained. It ensures air needed by plant for respiration and may allow pollinators to enter into the greenhouse. Ventilation can also be controlled by using computers. A greenhouse system can be heated in a variety of ways. Solar energy can be stored and it can be used during the night or cold periods to heat up the greenhouse system. Waste from animals can also be used to raise the temperature inside a greenhouse system. Electronic controllers can be used to keep track of the temperature inside a greenhouse. Normal thermometers can be used at different places in a greenhouse to know about the temperature condition of the greenhouse. A humidity sensor can be used to know about the humidity level inside a greenhouse system. The amount of carbon dioxide inside a greenhouse can be increased. Cornerways Nursery in the UK is deliberately set close to a noteworthy sugar refinery, devouring both waste warmth and carbon-dioxide from the refinery which would somehow or another be vented to environment. The idea of greenhouse first came from the Roman. A roman emperor used to have a kind of cucumber daily and the farmers used artificial techniques, so that they can present it daily to him. Netherlands has buildup the biggest green houses in the world and few of them are so huge that they can be used to produce millions of vegetables and fruits every year. Lighting and shading can also be done inside a greenhouse. It is secured as security measures can easily be taken by setting up cameras or pressure pads inside the greenhouse.
