I have long wondered about the overall determination of the amount of umols a plant receives. When you test the output of your lights at say 24 inches, that is usually testing at the top of the canopy level. But what about those areas below the canopy top? Does the plant distribute the received light values throughout the plant, or does each bud site on the plant need to be illuminated independently? That is, if my canopy top is receiving 500 umols, do I need to add additional side lighting to increase the amount of umols that those lower branches receive? Perhaps this is a stupid question, but I have always wondered and have never found any satisfactory information concerning it. Thanks in advance to anyone who can offer an answer.
