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.
