Where should the plant light be placed?

The grow light can simulate ideal lighting conditions, so the location of the grow light is also very important, and the ideal position is to hang directly above the plant, so that the leaves on all sides of the plant can also be exposed under the grow light, but It should be noted that we need to adjust the position of the grow lights according to the plants we are planting, and keep an appropriate distance. Take fluorescent lights and LED grow lights as examples, they have less heat dissipation. Generally, it is recommended to hang them 50-100CM away from the top layer of the plants.
