Dutch tulip grower installs "dynamic" LED lighting to steer specific growth characteristics

Philips Lighting has installed dynamic growth lighting at Dutch tulip grower Karel Bolbloemen in Bovenkarpsel, the Netherlands.

The system makes it possible to adjust the light recipes during the course of the growth cycle to promote specific growth characteristics, such as stronger stems for its tulips.

With the Philips GreenPower Dynamic LED horticultural lighting both the LED colours in the spectrum (far red, red, white and blue) and light intensities are individually adjusted using software controls. This level of flexibility in a lighting system is beneficial as Wageningen University research reveals that tulips respond differently to various LED-colors.

The new controllable system from Philips Lighting gives researchers and growers like Karel Bolbloemen more insights and options for growth optimisation since an unlimited number of light recipes may now be used using the same light source. The lighting can be tuned with precision to improve the quality of the tulips and reduce failure-rates. The flexibility may also be used to better match production to satisfy peaks in demand.

Owner Bert Karel said: "The new Philips GreenPower LED lighting system gives us the flexibility to adjust light recipes at any moment of the day which gives us new insights to optimize plant growth. With the new Philips LED lighting system it is possible to keep the tulip stems short and compact which makes the tulips stronger."

Karel Bolbloemen started in vertical farming in 2011, which makes them one of the first tulip companies in the Netherlands to adopt large-scale internal expansion with multi-layer cultivation. In this multi-layer area of 3,000sqm the tulips are propagated from the start in four layers in containers with an ebb and flow system. The tulips remain in the dark for the first few days to germinate, before LED lighting is added.

Philips Lighting business leader Udo van Slooten said: "This is a breakthrough innovation. Now with just one lighting system, researchers and growers have the flexibility and precision to fine tune LED light spectra and intensities to steer specific growth characteristics of plants and crops. It gives tulip grower Karel Bolbloemen the flexibility to adjust the light recipe over the growth cycle of his crop to meet the perfect growth needs of its tulips." .

Van der Laan installed the lighting system.
