sooooo? is far red good or bad? sounds bad,..i find your post informative but confusing!from When Reds & Blues Collide: Understanding Light-Related Plant Physiology
Far-red light between 730 and 770 nm also plays an important role in plant development. Increased amounts of far-red light typically indicate a shaded environment. Phytochromes give the plant a way to sense relative ratios of red and far-red light. When this shading effect is detected, physiological changes are triggered that lead to the stretching of plant leaves and stems. This behavior evolved to enable plants to reach above their neighbors competing with them for light, offering the tallest plants the advantage of unshaded lighting.
