The study, which will go on for 18 months, will provide information about the effect of 100% LEDs on the quality and branch weight of roses. The trial ties in with the principles of The New Cultivation: an energy-efficient method of cultivation combined with optimal production. The project is receiving support from the Rose crop cooperative and is partly financed by ‘Kas als Energiebron’ (‘Greenhouse as a source of energy’), the Dutch Ministry of Economic Affairs' and ‘LTO Glaskracht Nederland's’ innovation and action program.
The aim of the study is to demonstrate that cultivation using 100% LEDs is possible. LEDs are the key to efficient, energy-saving cultivation, which also makes for a better-quality end product. Higher and higher light intensities are being used in rose cultivation because the crop performs best under these conditions. Lamps that use old technology produce excess heat. With LED toplighting, higher light levels can be achieved with less excess heat.
