De Boer is satisfied with the results
In addition to moisture regulation, the system has another major advantage: regulating the temperature. In illuminated crops, you have to deal with light emission rules, whereby the screen must be closed at certain times. This can cause the temperature under the screen to rise considerably. Every 10,000 lux Son-T lighting means an increase of 6 to 7 ͦ C. To prevent this, we also use the fans for cooling.”
I get goosebumps from how evenly it colors
Paul and Marcel van den Broek are very pleased with the system. “The temperature distribution is much better in the greenhouse. You can see that in the crop. I get goosebumps from how evenly it colors ”
The aim is to keep the RH at 87% under closed climate screens, and that works well. In the old greenhouse we have to set up the air vents above closed screen much more often.
More active crop and a stable climate
We are satisfied with the HinovaFan. We grow more generatively, we have a stable climate which ensures an active plant. Since using the HinovaFan, we have noticed that we have a more active crop and a higher water absorption.”
Energy savings and better controllability are the benefits
Gapping the screen is the cheapest solution, but this creates a cold air flow and you have to turn on the heating pipes to dehumidify. And we didn’t want that.”
Creating more air movement was the solution
“The greenhouse was often clammy and stuffy. The greenhouse climate was not optimal for the crop. The plants were regularly too wet on the inside, which led to problems with rot and fungi, among other things.”The grower does not regret the investment. The vertical fans ensure more air movement and a more active and uniform greenhouse climate. First of all, the air movement is pleasant for our employees. They are happier and productivity is higher. The crop dries up faster, for example after spraying pesticide. As a result, we have less to do with fungi and other cultivation issues.”
