Abstract

How to grow roses with a constant quality year round in an energy efficient manner? That is the question for an applied research in which assimilation lighting, existing of HPS lamps and inter lighting LED, and cooling equipment and forced ventilation for semi-closed cultivation are combined. The crop management strategy and method of crop handling that goes with the strategy appears to be a key factor to control the ratio of stem weight and number of flower shoots. A continuous high humidity associated with the energy-efficient method of cultivation is unfavourable to keep the quality of roses. The savings on energy was 6% for electricity compared to practice and the energy from the sun collected during cooling was sufficient to heat the greenhouse. The savings on CO2 supply was 50% compared to practice. For the growers the combination of HPS, cooling and forced ventilation gives the best opportunity to grow top quality roses.
