(1) Plant different types of plants in a reasonable combination and arrange them according to natural laws. For example, when planting plants in the northern hemisphere, it is best to follow the principle of high in the north and low in the south, so that all plants can be evenly illuminated and try to avoid shading between plants;

(2) At the same time, reflective measures can be taken in the greenhouse to improve the effective utilization rate of light. When setting up the frame, reflective materials should be used. In addition, the frames do not need to be all upright at 90 degrees. Keep the middle frame upright and the frames on the north and south sides slightly tilted. This can increase the utilization rate of light by 5-10% and reuse it for plants.

(3) Cleaning the ceiling of the greenhouse planting. Clean the "ceiling garbage" regularly, otherwise the transparency is not enough, which has a great impact on the light and temperature in the greenhouse, thereby affecting the photosynthesis and respiration of the plants, and ultimately affecting the yield and quality of the plants.

(4) Reflective measures can be taken around the greenhouse to reflect a large part of the scattered light back and reused by the plants;

(5) Use LED plant lights to supplement light. On the one hand, the lighting distance can be appropriately shortened. Generally, when purchasing LED plant lights, they will be purchased based on the installation area and the irradiation area of the LED plant lights. The irradiation area can be appropriately shortened within a reasonable range to increase plant supplement light.

With the increasing demand for cannabis in various fields, not only has commercial cannabis developed, but indirect LED cannabis plant lights have also been further developed. The main factor for commercial cannabis plants is the supplementary light of LED plant lights. Cannabis can grow better with sufficient light and achieve excellent cannabis planting results.
