Effect of temperature and humidity on Cold Orchid

The best temperature for the growth of cold orchid is 20 ℃ 25 ℃. If the daytime temperature exceeds 30 mol, it will stop growing. Therefore, if you use greenhouse cultivation, in order to avoid indoor temperature is too high, in addition to shading, but also pay attention to good ventilation, in order to reduce the room temperature.

The winter temperature should not be lower than 5 ℃. It must be heated to avoid cold damage to the roots.

If the humidity is too high and the high temperature is encountered, the orchid plant is vulnerable to pathogens and has a bad effect on growth. When it is cold and dry in winter, a humidifier can be used to adjust the humidity. (you Chongkui)
