Jan Reijm, positive about test results Winterlight Greenhouse

"Think about how test results can be used to your advantage

Jan Reijm, of Komkommerkwekerij Reijm & Zn. grows cucumbers on the high wire in Berkel en Rodenrijs, together with his father. The company is about 4.5 ha in size, and Reijm & Zn. has bought a new company of about 8 ha. Next year they will still be growing bell peppers over there, but the intention is to grow 8 ha lighted cucumbers on the high wire in 2020. Reijm is supporting tests at Wageningen University & Research in Bleiswijk for the third year in a row. In 2016 in the 2SaveEnergyKas and in 2017 and 2018 in the Winterlight Greenhouse.

Do not look for arguments
Jan Reijm is calling this year's results in the Winterlight Greenhouse spectacular: one long cultivation of months thanks to earthing up, a top production, and an energy consumption of less than 20m3/m2. Asked whether the test greenhouse is representative of reality, Jan answers that you should not look for arguments, but that you have to want to learn how you can improve your company with the expertise from the test.

Working tidily
Reijm thinks the low disease and pathogen pressure in the test is remarkable. Maybe this is a result of working tidily and hygienically. He also tries to work more tidily at his own company, and pay more attention to labor. This repays itself in a higher production.

Dehumidifying with outside air
Reijm switched to a new cultivation adviser in 2018, and this has resulted in less screening in his company. Maybe that was responsible for less heating heads, although Reijm indicates this could also be a result of the light spring. In the future, he hopes to be able to invest in a dehumidifier, and close the screens more often again.
