Expand control and quality

Queen had been successfully using Philips LED lighting in multilayer 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 multilayer rooting phase Queen upgraded its LED production modules to the second generation of its kind, to further optimize 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.”
