I. Direction and Angle
During Greenhouse construction, the direction and angle of the greenhouse roof should be adjusted according to the greenhouse's usage period, production purpose, and the light requirements of the crops.

II. Location
The location of the Greenhouse is also crucial. Sufficient lighting is essential, especially in winter. Insufficient lighting in winter will cause the internal temperature to drop, requiring heating tools and increasing costs.
Using transparent materials on the exterior of the greenhouse is primarily for better lighting and heat dissipation. Therefore, the roof needs to be kept clean. Failure to clean promptly during rain or snow will also lead to insufficient lighting.
III. Air Circulation
Air circulation is an essential part of Polycarbonate Greenhouse design. For plants, a certain amount of indoor airflow can reduce the occurrence of plant diseases and prevent mold and mildew on leaf areas caused by excessive moisture.
For humans, proper air circulation can make people feel cool, increase the exchange of indoor and outdoor air, and improve air freshness.
If the greenhouse is too enclosed, the concentration of carbon dioxide produced by plant and human respiration will gradually increase, which is harmful to human health.
