Ideal for Soft Fruits Growers
Our open-field and soft fruit high tunnel greenhouses are perfectly tailored to the needs of berry and open-field crop producers. Designed to cover large areas, these commercial greenhouse solutions provide optimal protection against weather variability, enabling earlier planting, extended harvests, and higher-quality produce. By maintaining more stable growing conditions, our structures help increase yields, reduce crop losses, and lower operating costs, whether you’re cultivating strawberries, raspberries, or other delicate crops. From small farms to commercial berry operations, Harnois Greenhouses adapts to your goals and your climate.
Why use high tunnels for open-field & soft fruit production?
Soft fruits, such as strawberries, raspberries, and blackberries, are sensitive to weather fluctuations, pests, and short growing seasons. Our commercial greenhouse solutions offer key advantages:
- Earlier planting and harvesting
- Protection from rain, frost, and hail
- Improved fruit quality
- Better yield consistency
- Extended market access with out-of-season production
Whether you’re producing for fresh markets, local distribution, or agritourism, a greenhouse helps you increase your returns and reduce risk.
Greenhouse structures for soft fruits & open-field crops
Designed to protect large areas for commercial growers
Ideal for growers seeking reliable protection over large cultivated areas, our greenhouse solutions, specifically high tunnel systems, are designed to enhance crop quality, improve climate control, and support extended harvest periods.
These structures help reduce losses due to frost, wind, and heavy rainfall while allowing earlier planting and longer harvest windows. Whether you’re growing strawberries, raspberries, or field crops like tomatoes and melons, our greenhouses help you optimize space, labor, and seasonal productivity.
A perfect solution for soft fruits production efficiency
Higher yields and crop quality
High tunnel greenhouses for soft fruit production significantly boost both yield per square meter and harvest quality. By creating a more stable growing environment, these structures reduce crop stress and promote uniform growth throughout the crop.
Growers can increase planting density while maintaining quality standards, resulting in better fruit size, flavor, and shelf life. Predictable conditions also enable more accurate harvest planning, helping meet market demand and reduce post-harvest losses.
Lower input and labor costs
Our high tunnels are among the most cost-efficient greenhouse solutions for berry production. They require minimal mechanical intervention, reducing fuel and maintenance costs.
Harvesting operations become faster and more ergonomic, increasing the harvesting speed by up to 40%. These structures also support precise input management, resulting in a 50% decrease in pesticide use, optimized water efficiency, and minimized fertilizer waste, all of which contribute to a stronger bottom line.
Longer growing season & increased resilience
Thanks to their protective design, high tunnels enable growers to start planting earlier in the spring and continue harvesting later into the fall, even in colder climates. This extended season supports multiple harvests, increasing income stability, particularly for high-demand crops such as strawberries and raspberries.
The added protection also reduces losses due to frost, wind, and excessive rain, improving crop resilience and field productivity.
Sustainable & profitable crop management
Integrating high-tunnel greenhouses into soft fruit production enables growers to adopt more sustainable and controlled farming practices. By reducing chemical use, irrigation needs, and exposure to pests, growers can produce healthier crops with a smaller ecological footprint.
These improvements translate into faster ROI and greater long-term profitability. Harnois structures support both conventional and organic growers seeking to combine high agronomic performance with environmental responsibility.
High tunnel greenhouse
The recommended model for transitioning from open-field to protected soft fruits production
When it comes to soft fruits production, high tunnels are a proven solution to increase yield, extend the growing season, and reduce operational risks. Harnois’ high tunnel greenhouses offer the flexibility, ventilation, and protection that berry growers need, whether for seasonal or intensive production.
Designed for performance and cost-efficiency, this structure is ideal for strawberries, raspberries, blueberries, and other delicate crops grown in open-field conditions.
FAQ on greenhouses for open-field & soft fruits production
Can I grow strawberries year-round in a greenhouse?
High tunnels allow you to start production earlier in the spring and extend it well into the fall, even in colder regions. For full-year-round production, a heated and insulated structure, such as a gutter-connected greenhouse, may be required. Still, high tunnels remain the most cost-effective option for three-seasons growing.
What is the best type of greenhouse for raspberries?
High tunnels are often preferred for raspberries because they offer good ventilation and are compatible with trellising systems. They provide essential protection against rain and disease without creating excess humidity.
Do I need a permit for installing a field tunnel?
This depends on local regulations and the size of the structure. In most cases, small seasonal tunnels are exempt; however, it’s essential to check with your local municipality. Ask our experts and we will be pleased to guide you.
How do high tunnels improve soft fruits quality?
By protecting crops from rain, wind, and temperature extremes, high tunnels reduce physical damage and fungal pressure. This results in cleaner, more uniform fruits.
Are Harnois high tunnel greenhouses suitable for organic production?
Yes. Organic growers widely use our structures for berries and vegetables, as they support pest exclusion, reduce the need for inputs, and are compatible with organic certification standards.
