The temperature in the greenhouse is influenced by the amount of sunlight and ventilation. Greenhouses are intended to trap the sun's heat. The temperature in the greenhouse can be controlled by opening the door or opening the vents in the roof.
In many cases, greenhouse automation can be used to bring down the temperature. You can also visit some websites such as http://www.climatecontrol.com/climate-manager/ and many more to get more information regarding greenhouse automation.
Temperature control is easy to automate with the availability of tools. You can connect a vent in the roof to the trunk system that opens and closes the vents in response to temperature. You can even install heating greenhouses for certain seasons.
For the management of the greenhouse, the temperature should be right, there are some things that you have to follow. Plants will grow faster as the temperature increases daily. Thus, cropping time, or the time of harvest for precious plants, needs to be shortened. There is a greenhouse temperature difference between day and night since the night tends to be cooler.
To keep moisture levels down during the winter it is important to keep warm air inside. It may seem counterproductive but your plants will remain healthier.
In some greenhouses, you have to use certain methods to ensure the crops in certain seasons. Some devices that you can use are like additional lighting that mimics the sun during the morning hours and late afternoon hours. You can also use the greenhouse heater to increase the temperature. All these devices can be controlled by a greenhouse computer so you do not have to do it manually.
