USA High Tunnel for Cut Flowers Growing
A high tunnel for cut flowers suits growers seeking rain and hail protection at lower cost than a closed greenhouse. Especially effective for chrysanthemum, sunflower and tropical flowers that tolerate natural ventilation well, where the main risk is physical damage from heavy rain. For growers supplying local and regional markets, a high tunnel significantly improves quality and reduces weather-related waste.

Stem and bud rain protection
Heavy rain breaks growing stems and physically damages buds, a high tunnel eliminates this risk that can destroy 20-40% of production during rainy season.
Lower investment to scale acreage
High tunnel cost per square foot allows covering 3-4× more area than a greenhouse, increasing protected flower volume with the same budget.
Ideal ventilation for tropical flowers
Flowers like heliconias, sunflowers and chrysanthemums benefit from natural ventilation through open ends, preventing foliar disease without the cost of active ventilation systems.
Agronomist Tip
Install additional anti-hail netting on the sides of cut flower high tunnels during peak storm months, lateral hail entering through open ends is the primary cause of crop damage in protected flowers in highland areas with frequent thunderstorms.
