Polyeco Greenhouses are meticulously engineered to provide impressive wind resistance, capable of withstanding winds of up to 65 mph when anchored properly. For added resilience, models like the Polyeco Classic can endure even higher winds, especially when ground anchors are securely concreted in place. To further enhance wind resistance, consider strategic placement of your greenhouse in a less exposed location and the use of concrete for securing ground anchors. These measures ensure that your Polyeco Greenhouse remains steadfast and reliable even in challenging weather conditions.
