In Hellevoetsluis, a cannabis grower operating in a former tomato greenhouse has been given extra time by the court to implement measures that should put an end to odor complaints from the surrounding area. This decision follows a long-running dispute between the grower and the local municipality, which has been under pressure to act after a wave of complaints from neighbors.
The grower, CanAdelaar, had requested a provisional ruling after being hit with a penalty order in late June. The judge upheld the penalty but granted a longer grace period, giving the grower an additional four weeks to get odor-control measures in place.
If, after September 4, 2025, odor issues are still detected, CanAdelaar faces fines that could reach as high as 2 million euros. Part of the penalty order also requires that all greenhouse windows and doors remain closed. Following the Rotterdam District Court's ruling on August 7, this requirement now takes immediate effect. The grower had argued against it, warning that keeping the greenhouse sealed would cause the entire crop to die within days.
Meanwhile, CanAdelaar has been working for some time to reduce the odor problem. The company has ordered around 120 additional odor-filter units for installation, experimented with a misting system (though the regional water authority has not yet approved its use), and is setting up extra extraction systems to remove and centrally filter air from flowering plants. In addition, an odor expert is close to completing calculations on which technical solutions could realistically meet the legal odor limits.
