Barely a hectare
My wife and I have worked for years growing cucumbers in our greenhouses on Oude Leedeweg in Pijnacker. We grow our cucumbers on an area of 7400 square metres, which is barely a hectare. The yield is calculated based on the number of cucumbers produced per square metre. On an annual basis we produce 170 cucumbers on one square metre. That's a pretty impressive figure for consumers - so many cucumbers from such a small part of the greenhouse.
