Answer: The watering time for vegetables in winter greenhouses should be good before and after noon, because the temperature in the shed is high, and the side effects after watering are relatively small. Watering in the early morning and early evening should be avoided to prevent freezing of vegetables. When using water, well water should be used as much as possible because the high temperature of the well water can reduce the physiological stimulation to the vegetables.
