The paradigms that have been devised from model plant systems indicate that light quality plays a central role in controlling events coincident with seedling establishment as well as the commitment to flowering.  Our interest is to utilize the new breakthroughs in LED technology to provide developing plants with supplemental wavebands in an effort to skew plant growth and development.  In other words, the addition of narrow bandwidth red, blue, far-red or even green light can alter plant form and function.  These low-energy, low-cost, long-life resources allow researchers and potentially growers to tailor light treatments to adjust plant growth and development.  This is an excellent alternative to the application of growth regulators, especially in food-crop production.
