There was a great deal of research and experimentation before Sylvania engineers attainedphosphor blend that proved to be the most effective in stimulating propagation of plants.The answer was a balanced blend of red and blue radiations which, when tested incontrolled experiments by both commercial growers and university laboratories,proved superior to all other lamp colors tested.The color rendition produced by GRO-LUX plays a iwo-fold part in plant growih,(1) furnishing energy for making carbohydrates and (2) governingphoto reaction of responses.
