ABSTRACT

A greenhouse is an area where plants are grown in a controlled atmosphere. Greenhouses recreate the environment necessary for plants to grow year round in areas where that would not be possible otherwise. Humidity, temperature and sterility are all environmental conditions kept at a constant by a greenhouse. The conditions in the greenhouse, contributing to crop yield, called the greenhouse microclimate. They can be defined as those climate variables to which the vegetation in the greenhouse and be exposed include: temperature, radiation, carbon dioxide levels, humidity, and wind speed. This is illustrated in Figure 1. The energy and mass exchange between the outside air and the greenhouse effect on its microclimate. These exchanges can be described with the energy of the greenhouse and the amount of mass. The energy budget - the balance between the inner and outer flow of energy in the greenhouse, while the mass budget assumes input and outflow of the mass (water vapor and carbon dioxide). These budgets are influenced by the structure and design of the greenhouse, the environment, the state of the plant and management decisions. These effects are further discussed in this article.
