background
Continuous innovation has made Queen? one of the world's leading potted and fresh-cut longevity flower growers. Since 1939, the Danish company has integrated its technical knowledge to produce longevity flower products with perfect flowering, leafy fleshy green, longer shelf life and leading market. “All plants are naturally viable and can withstand longer dry and hot environments than other brands of plants,†said Frenz Jepsen, general manager of Queen. Kai L?nne Nielsen, R&D and production manager, leads the R&D team and works at the 12,0000-square-meter base in Aarhus, Denmark. The facility includes modern greenhouses for the production and cultivation of high-quality virus-free seedlings, as well as climate chambers for optimal climatic conditions. The global horticultural counterparts are extremely reliant on the award-winning longevity flowers developed here.
challenge
Since 2006, Queen has successfully applied LED lighting in multi-layer cultivation facilities. However, high-pressure sodium lamp lighting is still used in the greenhouse, so flexibility is limited, and heat production is excessive, which reduces the growth rate. “We are always looking for ways to optimize and speed up production.†Frands Jepsen said, “We want to find a 100% LED lighting solution.†Applying high-pressure sodium lamps in multi-layer cultivation facilities, heat production is not conducive to cultivating popular longevity flower products. . Queen's longevity flower plant type is more compact and favored by customers. Excessive heat can make plants grow, so Queen has been looking for ways to reduce plant temperature to ensure more stable plant quality. Like most growers, Queen is also pursuing more efficient use of planting space. High-pressure sodium lamps can cause severe shading in the greenhouse, further reducing efficiency, wasting space use, and affecting Queen's economic benefits.
solution
With a botanical expertise and market reputation, Philips Lighting can help Queen solve the challenges. “We have a long-term relationship with our partner Horticoop Scandinavia,†says Frands Jepsen. “We think Philips has a reliable product solution and market reputation.†Before deciding on the LED solution, Queen tested different spectra to find the most Good LED products for crop growth. In 2017, Queen applied Philips LED plant lighting in three cultivation stages. In the rooting stage of multi-layer cultivation, Queen upgraded the original Philips LED production module to the second generation, further strengthening control and optimizing flexibility. In addition, the company's refining room is equipped with GreenPower LED top light module, which will be adapted for two days before being transplanted to the greenhouse. Finally, Queen supplemented the GreenPower LED top light module for the existing high-pressure sodium lamp ceiling lighting in the greenhouse for the vegetative growth stage of longevity flowers.

benefit
After expanding the LED lighting application, Queen gained complete control over the entire cultivation process. “Longevity flowers benefit from the red spectrum of LEDs,†says Frands Jepsen. “The rooting speed is 2-3 days faster and 25% faster throughout the year.†Cool LED lighting means Queen can add lighting during the summer planting stage, no need Worried about generating too much heat. In Denmark's long, low-light winter, Queen can increase the light level by 30%. In the greenhouse, the supplemental Philips LED top light module helps to reduce costs, especially during the period from the end of spring to the beginning of winter. The LED top light module uses less power, which is an important consideration for Queen to make the final decision in order to extend the lighting time. When the light intensity in winter is reduced, the cost of electricity is also reduced. Queen uses a more balanced hybrid lighting mode combining high-pressure sodium lamps and LED dome modules. “The LED top light module increases the number of shoots in the plant by 15%,†Jepsen said. “We also found that the plants have more side branches and more buds per side. The increase in long days of sunshine also means Queen’s Plant spray growth regulators are also reduced, which also saves a lot of money."
