In the past years important steps have been made in the research into growing roses under LED-lighting. It started with growing under traditional lighting (HPS 200 umoll) together with various systems to close the greenhouse as much as possible, but now they want to make the next step to the future of growing roses: 'Full LED'.
The national commission Roos has, in conjunction with Wageningen University & Research and GreenQ, started a new project for the next two years. The entrepreneur group Energie has recently agreed to the next phase of the LED-research of the rose: 'perfect rose: the next level.' During the general meeting of the crop cooperation Roos last January the growers present were already positive about the progress of this research.
Input experience proves useful
As Richard van der Lans (Arends Roses), member of the national commission Roos, indicates: "We think growing under full LED is the way of the future. The high efficiency of the currently available installations is already 3 Mol per watt (HPS1,75). This is already an improvement of more than 70% per kw! The armatures give off more light and less heat, which should offer us the option to grow with more light and to better deal with heat. Liberalization of the current screen rules is not to be expected, it will be hard enough to maintain those as they are now. In the next two years we have to prove that growing roses under full LED is possible. Various technical means to achieve climate optimality have been researched and introduced, partially because of the intensive guidance from the field. For this reason we deem it important that all members of the crop cooperation visit this test and contribute to the project in this way."
Rotation schedule
To increase the involvement of the growers, a rotation schedule has been made. The commission meets every Friday afternoon at the Delphy Improvement Center. Members of the crop cooperation will be asked which data (two consecutive weeks) they can visit the test. In the next two weeks the members of the crop cooperation will be asked to formally grant permission for co-financing the project.
