Blue light has been shown to have the most efficient photosynthesis activity, meaning it provides the most energy for plant growth. By using a filter that allows only blue light to pass through, the gardener can reduce the overall light energy while still maximizing plant growth. Additionally, blue light is known to inhibit stem elongation, which can help keep plants compact and better suited for a greenhouse environment.
