Light is the basis of plant growth. Without light, there is no photosynthesis and it is impossible for plants to grow. After entering the winter, the light gradually weakens, and the lack of light often occurs in the shed, resulting in slow growth of the vegetables, low yield, and low benefit. Especially when it comes to cloudy days, the lighting in the shed is extremely weak, which seriously affects the normal growth and development of the plants. Therefore, in the deep winter low temperature and low light season, especially when it comes to even cloudy days, it is necessary to fill the shed.

How to fill light? Many vegetable farmers believe that since it is a fill light, it should be after the shed. Is it not an extra measure to fill the light during the day? In actual fact, under cloudy conditions, it is only reasonable to make light after pulling the shed during the day.
Even in cloudy days, supplementing light during the day is beneficial to the accumulation of photosynthetic products. Because even in the open sky, the light intensity of scattered light is only 3000-5000 lux. Although the light intensity is above the light compensation point of most crops, the intensity is very weak. The plants can only maintain self-sufficiency when they see the light, but there is no accumulation of the remaining photosynthetic products, and they cannot supplement the night's respiratory consumption. The plants are still in the state of “eat the oldâ€, with lack of nutrition, poor resistance, and diseases that are easy to infect. For a long time, the plants will even “starve to deathâ€. Filling the light during the day, combined with the intensity of the scattered light, allows the plants to receive more light, more photosynthetic product accumulation, and supplies respiratory energy.
Moreover, the high temperature during the day helps improve the photosynthetic efficiency. Photosynthesis is greatly affected by temperature. In even cloudy days, even if the diffused light is accepted, the temperature in the booth is higher than the nighttime temperature. At higher temperatures, photosynthetic enzymes are more active and the photosynthetic efficiency of the leaves is higher. In other words, under the same light intensity, photosynthetic products accumulated more when the temperature was higher (with a certain limit).
Therefore, if you encounter a cloudy day and open the grass in the daytime to see the light, you should also arrange the fill light during the day to add more flowers, which is more conducive to reaching the purpose of light. Filling the light is best to use a dedicated fill light, according to the requirements of installation, timely fill light.
