A greenhouse (also called a glasshouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown. These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather.
This is one of the most important component. If there is no proper ventilation, greenhouses and their growing plants can become prone to problems.
Heating or electricity is one of the most considerable costs in the operation of greenhouses across the globe, especially in colder climates.
Cooling is typically done by opening windows in the greenhouse when it gets too warm for the plants inside it.
During the day, light enters the greenhouse via the windows and is used by the plants.
