What is the relationship between the weather and the price of vegetables?

Why has the price of cabbage become more expensive? The growth of vegetables needs sunshine, temperature, water and nutrition. 1 When it snows, the yield of vegetables that affect the light is less (rainy days). Vegetables need to be planted in greenhouses, and cold vegetables will slow down their growth in snowy weather. If the output of vegetables is small, the price of vegetables will definitely be more expensive. Many people understand this truth, so vegetable farmers and wholesalers will raise prices immediately, so as to ensure that profits will not decrease. And it's cold or snowy, so it's inconvenient to travel, so people will buy a lot of vegetables at a time, which will also make the demand for vegetables exceed the supply. These links are all at work. Do you think the affected vegetables should still be in transit or in the vegetable field that day? Sometimes the wholesale and retail of vegetables will appear on the dining table within one day. I wonder if you are satisfied with my answer?
