The development trend of the world, the Greenhouse facilities industry has rapidly from Central North latitude 25 degrees extend to north latitude 50 degrees, the more humid tropics area.  In these areas, labor situation, the available water and light and other factors are all very good. While countries in these regions, which have considerable economic capacity to improve, so the demand for higher quality products is also greatly enhanced.
The Greenhouse facilities  of subtropical or tropical regions required the following features:
1. Ventilation: Overwet humidity and retention air led lower yields, make it is difficult to control pests and diseases. It must have a better ventilation for air Change.
2. Rain function: Subtropical areas rains particularly frequent. It is still available to produce under heavy rainfalls situation, is very important.
3. Wind function: Having a strong wind is generally happened in the tropics , especially in Taiwan, typhoon, so the greenhouse structure design must also be strengthened, or use the more wind-resistant structures, can fit the actual needs. And need to rebuild easily, to prevent the damage of Typhoon, can Immediate reconstruction.
4. The ability of cooling and shading: As is often the high temperature, it must be able to take advantage of a variety of low-cost way of cooling operation at high temperatures, To reduce the accumulation of heat in the greenhouse. Light regard must also seek to regulate and control, Or use shading to reduce the solar radiation, making it suitable for plant growth.
5. The appropriate heating capacity: It must have the ability to provide the right amount of warming heat in the winter, and the temperature required for the crop.  In the cold and wet winter, heating can reduce humidity, and maintain a warm environment crop.
6. The ability of insects and bacteria: Subtropical regions of high temperature and high humidity, will easily become a breeding ground for insects and germs. Therefore, the greenhouse itself must have more effective pest control and disease prevention facilities. Although many of the studies currently underway to try to net curtain to prevent insects invade greenhouse, but the effect is still less.

Inverter Micro-mist Humidifier system which can be in the greenhouse facilities, irrigation, fertilization, cooling, humidification and fully automated pesticide spraying and other work.
