First, open the window to ventilate regularly

The top of the glass greenhouse will be installed staggered windows natural vents, vents are set in the top of the tip of the side of the high point of the position, the top of the glass ventilation window size is 2 meters by 1 meter, the top of the sun panel ventilation window size is four meters by one meter. If the glass greenhouse greenhouse for a long time for the closed state, then the humidity in the shed will naturally rise, so in the right time appropriate ventilation is a good way to reduce humidity.

Second, increase the amount of light transmission

We can increase the light in the shed by opening the glass greenhouse outer shading system, inner shading system. Increase the amount of light transmission can improve the room temperature, only after the room temperature rises, we can carry out normal ventilation.

Third, warming and humidity reduction

The use of this method can not only meet the needs of vegetables on the temperature, but also reduce the relative humidity of the air. When the plant grows to have resistance, watering closed shed warming up to about 30 ℃ for about an hour, and then ventilated to remove moisture, 3, 4 hours after the shed wet below 25 ℃ can be repeated once.

Fourth, reasonable watering to reduce the source of humidity

Moisture is the main factor leading to an increase in indoor humidity, so how to watering has become an important measure to control humidity. Winter and spring production can choose a sunny day ditch watering or split watering, film cover can be used under the membrane dark irrigation. Watering should strictly control the amount of watering to prevent excessive indoor humidity. After each watering appropriate wind, timely hoeing loosening, can reduce soil humidity, but also can reduce air humidity.

Fifth, choose the right insulation curtain material

Moisture permeability and hygroscopicity of good insulation curtain materials, such as non-woven fabrics can prevent the inner surface of the condensation, and can prevent dew from falling on the plants, thereby reducing air humidity.
