The direction of the greenhouse is important due to the shadow that the greenhouse skeleton creates and the air circulation in the greenhouse is essential due to the growth and growth of flowers and plants and should be taken into consideration both.

Direction of greenhouses

The greenhouse skeleton creates a shadow and depending on the angle of radiation, these shades are different. The need to pay attention to this is especially important in winter production, as slight changes in the percentage of light reached to plants can play an important role in the quality and quality of production.

The location of the greenhouse should be such that it receives the highest amount of light. The first choice for the greenhouse is in the southern or southeast view. Light all day provides the best conditions for the plant. Of course, the light shining from the east is sufficient for plants in the morning. Morning light has the most utility, as plants are allowed to start the food production process earlier and this will result in maximum growth.

Subsequent choices are southwestern and western view; Because it takes later light. The northern facade has the least desirability and is only suitable for plants that require little light. Crystalline trees such as maple and oak can effectively of intense light
Summer afternoon reduces shadow. It should be noted, however, that the trees do not shade on the greenhouse in the morning. These trees in the winter allow enough light to reach the greenhouse; Because in the fall they lose their leaves.

The flow of air in the greenhouse

Air circulation in the greenhouse is essential. When a plant is exposed to fresh air outside the greenhouse, fresh air is provided near the leaves and the plant can return oxygen and use fresh carbon dioxide.

The airflow also helps keep the relative humidity down and control the temperature in the greenhouse. Commercial greenhouses depend on all the requirements mentioned above and even more.

In a commercial greenhouse is the main purpose of profitability; To achieve this, the greenhouse must be effective in providing the desired environmental conditions. The light and temperature of the greenhouse should be strictly and seriously controlled. Computers have recently been widely used for such controls.

Also, the presence of toxic and dust gases in the greenhouse may be a serious problem. These gases include carbon monoxide, nitrogen oxide, and nitrogen dioxide; That may be emitted from thermal equipment
