How to build a shed in the nursery and how to net it

For areas with occasional low temperatures below zero degrees Celsius and frequent continuous rain and torrential rain, it is better to cultivate orchids to build a plastic greenhouse and a movable shading net. In the normal temperature period and high temperature period, open the surrounding plastic film for ventilation, and make the orchid plant bathe the saturated moisture in the air close to the ground at night, so as to form dew on the surface; close the greenhouse in the low temperature period, and when there is light, lift the east-west plastic film to ventilate. This facility can adjust the temperature, humidity and light to facilitate the growth of orchid seedlings. (Xu Dongsheng)
