There is no single distance that works for every grow light and every crop. For commercial growers, indoor farm operators, greenhouse project buyers, and cultivation equipment distributors, the better question is: how close can the grow light be while still giving the crop even, useful, and safe light across the whole canopy?
Many buyers become disappointed because they choose lights only by wattage or appearance. A lamp may look bright to human eyes, but plants respond to usable light energy, lighting duration, distance, and canopy coverage. If these factors are not planned correctly, the grow room may still face slow growth, uneven plant size, weak flowering, or higher electricity cost without the expected output.
