At our Hydroponic Center you can see the trials and demonstrations for all our existing and new hydroponic lettuce varieties, in the middle of our daily breeding activities. This is unique in the world!

It is an inspiring environment for selecting what to grow next season and providing you fresh ideas, such as the Nunhems multicolor mixes with fresher colors and a longer harvest window.

We kindly invite you to come, see and discuss which variety is the best fit for your company, cultivation method and your customers.
