One is to increase the humidity inside the shed. At night, the greenhouse sheds and air vents have been closed, the shed temperature is lowered, the humidity in the shed is gradually increased, and fog can be formed. The relative humidity is over 100%, and it can be gathered into dew on the cucumber leaves. If watering is carried out at night, it can be described as "adding frost", which can increase the humidity in the shed and easily form a low-temperature and high-humidity shed environment, which is conducive to the occurrence and spread of diseases. For example, the optimum temperature for cucumber downy mildew is about 18 °C, and the humidity is above 83%.
The second is watering at night, easy to root, and roots. Because the metabolism of cucumber roots is slow at night and the resistance to stress is poor, if the cold water is suddenly poured, it will have a greater impact on plant growth.
Under normal circumstances, watering in winter is better than watering before 10 am on sunny days.
