The number of buds increased up to 15% after having installed LED toplighting– Frands Jepsen, Managing Director of the Queen brand
The challenge
Since 1939, Queen has bred kalanchoes to make them more compact, something its customers value. “We are always searching for ways to optimise and speed up our production processes,” says Frands Jepsen. “We wanted to find a way to produce our plants with only LED, as heat can cause the plants to stretch." Queen was looking for a way to reduce plant temperatures to provide more consistent quality.
The right lighting
Queen had been successfully using Philips LED lighting in multi-layer configurations since 2006. But their greenhouse area still used HPS fixtures; limiting flexibility, increasing heat and reducing growth rates. By expanding its LED lighting to three cultivation stages in 2017, Queen has gained immense control over its entire growth process.
In the multi-layer rooting phase, Queen upgraded its LED production modules to the second generation of its kind, to further optimise control and flexibility. 'The kalanchoes really benefit from the LED’s red light,' says Frands Jepsen. 'We get two to three days faster rooting, which is 25% faster, all year round.'
In the greenhouse, Queen added GreenPower LED toplighting to its existing HPS toplighting for use during the kalanchoe vegetative phase, the long-day phase of the crops. 'LED toplighting has led up to 15 percent increase in our number of buds,' says Jepsen. 'We also see more side shoots and higher numbers of buds on each side shoot.'
Philips GreenPower LED toplighting
Philips lighting introduced a LED-based toplighting solution for greenhouse growers, easy to install and no need for water cooling systems.
