Ter Laak Orchids
The Netherlands

Ter Laak Orchids – owned by the brothers Eduard and Richard ter Laak – is one of the most sustainable phalaenopsis nurseries in the world. The family business,which covers an area of 125,000 m2, is well known for beingvery progressive.

By testing LEDs in
various colors

and in all phases ofcultivation we are not only seeing rapid results, but alsolearning a great deal. The most important thing is for usto find the best possible light solution for our crop.”


- Martin van Dijk, Cultivation Manager, Ter Laak Orchids

The challenge

During the three separate phases of phalaenopsis growth 
the plant requires specific standards of climate and light. Fundamental research has shown, for example, that the cooling phase can to some extent be replaced by lighting with deep-red light.

The right lighting


The trial is based on two setups of various colors o fLEDs, each of which covers a cultivated area of 120 m2. The trial area is 240 m2 in each phase of cultivation. This gives a total of 720 m2. Since there is already an HPS installation in the greenhouse, this will create a hybrid lighting system. The LEDs are suspended above the crop at particular points.


Philips GreenPower LED toplighting is a subsequent step in the development of light recipes for the growth of crops in greenhouses. The combination of different light colors within the spectrum makes it possible toincrease production and improve the year-round quality of the crop. This is an effective way of managing light levels in a highly focused manner.


A further benefit is the energy saved due to the higher efficiency of the LEDs. Although the trial with LEDs is still in its early stages, Ter Laak Orchids expects several advantages to emerge soon. For instance, Martin van Dijk hopes that the climate will improve as a result of a reduction in the radiant heat from LEDs compared to HPS lamps.
