Plants achieve better growth when they are exposed to specific wave lengths of the electromagnetic radiation spectrum. Older lighting technologies utilised broadband lighting as a shotgun approach to try and achieve plant growth.

However, broadband systems present the commonly accepted defect of emitting a limited spectrum. The light that these systems produce is unbalanced. Wavelengths of light that are useless to plants are emitted from these systems, limiting their efficiency. Much of this extra light results in more heat, which is not beneficial to plant growth. As detailed above, getting rid of the excess heat requires complex engineering and expensive systems to be implemented. 

In contrast, LEDs have the ability to produce wavelength specific light. This is the biggest advantage of LEDs in the indoor growing market. Because each LED emits a specific wavelength, growers can now optimize lights for plant growth. By mixing various LED chips, a complex light spectrum can be created as unique formulas for different growth conditions. Although we know that plants benefit mostly from the blue and red parts of the spectrum, making the best light is not as simple as using random blue and red LED chips. There are specific wavelengths that are ideal for plant growth. Different ratios of red and blue light will affect different types of chlorophyll (the main center of photosynthesis). Not only that, plants need different wavelengths during different phases of growth. For example, plants benefit from the red spectrum during the flowering phase. 

Results will inevitably vary from crop to crop, and even strain to strain. As this is an active area of research, scientists are discovering more everyday not only which wavelengths benefit plants, but during what time of day or which growing phase to use them. Growers may even be able to limit their use of Plant Growth Regulators (PGR), since these special wavelengths would be optimized to produce similar results. Aside from cutting down costs, this gives the grower one less task to worry about. With more research, growers will better know which spectrums can accelerate or slow down growth, improve yields, or morph the shape of different plants.
