1、 Winter planting requires the use of plant lamps, as there is less light in winter and plant lamps are needed to supplement the light.

2、 Indoor planting environments, such as planting succulent or other ornamental plant types, require the use of plant lamps to adjust the spectrum and make plant growth appear beautiful.

3、 When planting off-season plants or other plants in greenhouses, the intensity and duration of light both affect the growth of the crops. If the light intensity is lower than the compensation point of the crops, it will make the organic matter produced by photosynthesis unable to keep up with the rate of consumption, which will affect the growth of the plants and seriously lead to death. Under low light conditions, plants may also exhibit signs of elongation and weakness. Under the influence of cloudy and haze weather, the lack of light is even more pronounced, leading to a sharp decrease in photosynthetic rate and causing serious losses due to diseases and pests.
