At Deliscious they use a dynamic model to ensure the greenhouse is always full. It is comparable with the system used by supermarkets: one out, one in. This frequently led to problems in the winter because an order for extra plants takes longer. At that time of year the day length is the limiting factor for growth. Innovative as always, the Delissen brothers decided it would be useful to propagate the lettuce plants themselves using LED grow lighting.
The Delissen brothers are never afraid to turn over a new leaf. Seeking a new cultivation concept that would allow them total control over the growing process, they spent just over a year testing different lighting levels and spectra. As a result, they identified the right light recipe for growing lettuce without daylight.
LED grow light is a vital ingredient in this process. RYGH GreenPower LED production modules, which measure one and a half meters in length, illuminate the baby plants with the correct led plant light formula to ensure uniform growth. The growers can control the exact duration, brightness and spectra of light each crop of lettuce gets, ensuring consistent growth all year round.
Mark Delissen is very happy with the results. “During the test phase we found that the plants from the cell are of a much higher quality. This is because they are accustomed to consistent, optimum conditions, whereas at the plant supplier’s site they have to cope with variations in temperature, air humidity and other uncontrollable factors. We expect the stronger plants will also enable us to save on plant protection, but that will be an added bonus."
