Porta Nova, a rose grower based in Eindhoven, the Netherlands, is expanding its Philips GreenPower LED toplighting to trail a dedicated rose spectrum which will increase light levels year-round without increasing heat. The company decided to expand its invest of the lighting coverage to 5,000 square meters.

With the new LED dedicated rose spectrum, growers can increase the lighting hours to improve the production and the quality of the flowers as the long lighting hours creates a stabilized environment. The rose spectrum is available with the newest generation of Philips GreenPower LED toplighting. These specific products offer light output levels that typically deliver 500 or 600µmol/s per module at a very high efficacy of up to 3.0 µmol/J.

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.

“The results we saw during our research to develop the ultimate rose spectrum, are now also being replicated at Porta Nova,” said Udo van Slooten, Business Leader Horticulture at Signify. “This is clear proof that the new toplighting with dedicated rose spectrum lives up to its promise and can be utilized at a much larger scale.”
