Plants that turn on lights at night undergo photosynthesis, which mainly relies on red, purple, and blue light. Each plant has similar lighting requirements, and as long as they can emit these two types of light, they can be absorbed and utilized by their leaves for photosynthesis. If the cultivation period of plants is continuous cloudy and rainy weather, it is necessary to use artificial lighting to supplement the light. Adequate light can help plants grow better, and flowers and plants can also bloom.

Can turning on the lights increase the opening and closing effect

Sure, lights can also emit red and blue purple light, which can be absorbed by plants for photosynthesis. In flower production, lighting plants is used to enhance their photosynthesis and flower early. Green plants can produce oxygen through photosynthesis under light irradiation, and the intensity of light must reach a certain level. The effect of light on plants increases with the increase of light intensity above the light saturation point. When the light saturation point is reached, photosynthesis decreases with the decrease of light intensity. When it reaches a certain intensity, the CO2 absorbed by photosynthesis and released by respiration are in a balanced state. At this point, the light intensity is called the light compensation point. At this point, plants can no longer engage in photosynthesis. So, to be precise, photosynthesis can occur when the light intensity under illumination is above the light compensation point of the green plant, and cannot occur when it is below the light compensation point of the plant.
