Before we know what types of greenhouse structures are, we first need to know what greenhouse structures are called. The greenhouse is a limited space that provides the ability to control the appropriate environmental conditions for plant growth. In fact, the Flower House is a structure covered with transparent or semi-transparent covering material. Agricultural greenhouses can control all or part of the factors that contribute to growth.

In other words, a greenhouse is an abnormal structure that provides optimal conditions for the growth and production of the desired agricultural crop throughout the year. The internal conditions of the greenhouse (microclimate) are controlled by growth factors such as light, temperature, humidity and air composition, which can be effective in increasing production. According to this definition, the term greenhouse function creates the necessary conditions for growing a crop
