Van der Knaap is known for its substrate knowledge, but did you know they also developed a sustainable cultivation system? The liquid nutrient solution rich in organic NO3 that is produced with this system is also extremely suitable for other cultivation systems, such as growing lettuce in a hydroponic system.

The hydroponic section in the company's innovation center has recently been redesigned and all ponds now receive a 100% organic nutrient solution. The earlier phase of their research has already proven that the organic fertilizer holds its own compared to mineral fertilizer. On a number of points it even surpasses the traditional method, they report.

The follow-up research now focuses on influencing the cultivation by means of different pH values. In addition, the young lettuce plants get a good start on Obturo plugs or conventional pressed pots.
