Eindhoven, the Netherlands – Since the introduction of Philips GreenPower LED Toplighting Compact from Signify (Euronext: LIGHT), the world leader in lighting, many vegetable, fruit and horticulture growers have made the choice to fully equip their greenhouses with LEDs. By combining this LED lighting with the GrowWise Control System, it is possible to both control and dim the light, giving growers a high degree of flexibility. This solution has now also found its way into lettuce growing; De Glastuin in Belgium opted for 100% LED grow lights from Signify.
Each type of lettuce requires a different amount of light. Heat is also a limiting factor when growing lettuce. As a result, in many periods it is not possible to illuminate the crops because too much heat accumulates in the greenhouse. Thanks to LED lighting, which emits less heat, it is possible to light the crop for longer hours, resulting in a increased production and faster growth cycles. The combination with the GrowWise Control System also allows the lighting to be dimmed. For example, to keep the light intensity the same on sunny days while maintaining light uniformity or to prevent climate fluctuations.
