Eindhoven – A lighting trial carried out on difficult to propagate patio plants with Philips LED GreenPower toplighting at Kernock Park Plants in Cornwall UK, reports an increase from 30% to 96% in propagation success rates for one crop and up to 75% in energy savings. Other benefits included faster rooting and improved crop quality, uniformity and control of botrytis. The energy-efficient LEDs also give off less heat and create a more uniform light distribution, making the module ideal for conditioned environments.
Kernock Park Plants propagates nearly 1200 varieties for its catalog, ranging from annuals to nursery stock, and trials a further 400 varieties on its 4 ha (10 acres) of glass and polythene greenhouses. The challenge is to successfully propagate as many high-quality plants as possible, especially those that are difficult to propagate using conventional HPS lighting methods. Using energy-efficient LEDS offers Kernock Park Plants the potential to increase production, profit margins on certain varieties and crop quality to strengthen its market share.
