In the past year, plant specialists from Signify have been working intensively with a research group consisting of professionals from the growing industry, academic field and public sectors. They cooperated to develop a dedicated light recipe with a LED spectrum for cut roses. The new cut rose spectrum has been developed specifically to grow high yields of top-quality roses in full LED in Western European climate conditions.
