Feb 6, 2017: With the aim to help rose nurseries in improving quality and increasing yields, Philips Lighting is associated with a trial of 100% GreenPower LED toplighting with a light level of 200 µmol/m²/s. The trail has begun at the Delphy Improvement Centre in Bleiswijk, Holland since April 2016.
The research will be conducted for a period of 18 months and is supposed to give information on the effects of 100% LEDs with regards to branch weight and quality of roses. Following the principles of The New Cultivation, the trial is focused on an energy-efficient process of cultivation joint with finest production.
The scheme will be partially financed by ‘Kas als Energiebron, the Dutch Ministry of Economic Affairs’ and ‘LTO Glaskracht Nederland’s’ innovation and action program. Also, the scheme is getting tremendous support from the Rose crop cooperative.
Rose production with 100% LED
The focus of the research is to display that cultivation of roses using 100% LEDs is possible. Arie de Gelder, project leader of the rose trial and researcher at Wageningen University and Research Centre said that LED lighting helps to improve the balance between heat and light which allows screens to be kept closed and creates a consistent weather.
Gelder further said that the major challenge is to be found in the plant heat at the top of the plant when contrasted with traditional lighting. It will be exciting to view how the rose plants respond to LED lighting and ultimately this mixture of temperature and light will provide rise to an additional development in quality with higher branch weight and big beautiful flowers, added Gelder.
25% reduction in power consumption
Philips said that by using LEDs in rose production, it is possible to get 25% reduction in power consumption as against traditional lighting. A mixture of heat pump and heat exchanges paves way for elimination of fossil energy ultimately taking a huge step towards sustainable cultivation.
Leontiene van Genuchten, plant specialist at Philips said that the company is set to move to higher light levels with LEDs along with control temperature and light in separation. Majority of the growers are convinced that HPS lamps are necessary for obtaining an appropriate crop temperature. Through this trial, it will be revealed whether similar results can be obtained using other means of cultivation, Genuchten added.
