Van Lipzig Tuinderijen


Van Lipzig Tuinderijen is a Dutch commercial cucumber grower, operating on 8.5 hectares.  Growing cucumbers on an area that spans about 17 soccer fields, the company grows 240 cucumbers per square meter, and is active between January and November of every year.

The company was established in January 2008 in Californië, a development facility which rents greenhouse space to agricultural entrepreneurs on a private basis. Van Lipzig chose to grow at Californië because of the large space it offered, as well as the facility’s high sustainability standards. Cultivation manager Peter van Ninhuys checks the crop-level dew point of cucumbers by monitoring temperature and humidity in combination with object temperature. To capture real-time dew point, a pointed temperature sensor hangs centimeters away from a pointed temperature sensor. Insights from 30MHz sensors, delivered to the ZENSIE dashboard, help van Ninhuys to optimize conditions in the greenhouses and reduce crop loss from mold and rot.

Saving energy

“With 30MHz technology, we’ve started monitoring the temperature of cucumbers— observing how quickly they warm up, and whether temperature falls below dew point. We track these metrics to prevent sunscald and mycosphaerella. In fact, after the first week of sensing, we realized that our tube settings were quite good, and our cucumbers did not have excessive moisture. We also saw an opportunity to lower temperatures and save energy” explains Van Ninhuys.

Temperature loss and root pressure

After monitoring the dewpoint of the cucumber fruit, Van Lipzig monitored the tops of cucumber plants to observe correlations with temperature loss and rain. Just two days into measuring, the company had gathered actionable insights. “We found out that the head temperature cooled very quickly after an unexpected rain shower. As a result, we adapted the screening strategy, so that the head temperature rose quickly to room temperature again. Now we are screening almost every night, preventing cold head problems. We think that this measurement makes it easier to monitor the root pressure. If the head does not cool too quickly relative to the root temperature, this causes less problems in cultivation.”

Affordable and reliable sensors

“Why did we chose to work with 30MHz? In horticulture we are very busy with making our cultivation methods as precise and sustainable as possible. Monitoring and gathering data is crucial here— and we think that’s a good thing. We’ve been on the lookout for affordable, reliable sensors, and 30MHz was a great fit.”
