What are the specific methods for building a shed and adding netting at the nursery site?

For areas that occasionally have temperatures below 0°C and frequent drizzly rain and heavy rain,cultivationorchidsit is best to build a plastic shed and add a movable shade net. During the normal-temperature period and the high-temperature period, open the plastic film on all sides for ventilation, and let the orchid plants bathe at night in the saturated water vapor in the air near the ground, so that dew forms on their surfaces; during the low-temperature period, close the shed, and when there is light, open the east-west plastic film for ventilation and air exchange. This kind of facility can regulate temperature, dryness and humidity, and the amount of light, so as to benefit the growth of orchid seedlings. (Xu Dongsheng)
