In a grow tent, we used the scientific research-grade optical radiation standard test instrument of Li-Cor company in America to carry out practical tests. The data showed that the distance from the plant to the grow light's luminous surface was inversely proportional to the size of PPFD, i.e. the longer the distance is, the smaller the PPFD will be. If the distance between the plant and the lamp reaches 24 ", the PPFD maintenance rate will be reduced to about 50%, which means that about 50% of the light energy is lost. In other words, the utilization rate of the grow light is only 50%. If the distance is longer, the utilization rate of the lamp will be lower. It should be noted that if there is no reflective film in the surrounding environment of plant factories and greenhouses, PPFD will decline faster and the utilization rate will be lower. Therefore, the best range for the PPFD is between 5 to 12. Based on the above tests, it is not difficult to see that the distance between the plant and the luminous surface of the lamp is between 5 and 12 inches, which is the best PPFD acquisition range.
