Located in Lanaudière, Les Serres Gourma is a specialized grower that focuses on producing high-quality culinary herbs for local markets. To meet the growing demand for fresh, local herbs, even in winter, the company turned to Harnois Greenhouses to install a structure that could extend its production season and optimize growing conditions year-round.
Driven by consumer interest in local and fresh ingredients, Serres Gourma sought a way to gain more control over planting schedules and crop cycles. The goal is to offer dill, basil, parsley, cilantro, and other herbs even during the colder months, without compromising on quality.
By incorporating greenhouse infrastructure into its operations, the producer increased its capacity, consistency, and resilience, while aligning with a more sustainable, short-supply-chain approach.
Choosing the right greenhouse for culinary herbs production
To meet their performance, durability, and scale needs, Serres Gourma invested in a Luminosa model greenhouse, a gutter-connected multi-span structure developed by Harnois. This solution was ideal for year-round herb cultivation in our local climate.
Main features of the Luminosa model include:
- Galvanized steel structure designed to withstand Quebec’s snow and wind loads
- Broad interior volume with high clearance, supporting optimal airflow
- Superior natural light diffusion for uniform herb growth
- Custom irrigation benches to minimize the impact of workforce
- Integration with heating, shading, and drip irrigation systems
This professional-grade structure supports consistent yields and reduces weather-related risks, two essential factors for herbs that are sensitive to environmental variations.
Why Les Serres Gourma chose Harnois Greenhouses
As one of Quebec’s innovative culinary herb producers, Les Serres Gourma required more than a simple growing structure. They needed a trusted partner capable of providing a turnkey and highly personalized greenhouse solution.
Les Serres Gourma selected Harnois not just for its structures, but for its ability to understand and support the construction of a 20,000 square metres controlled environment production.
Key reasons behind their choice included:
- A proven track record with Quebec-based herb and vegetable greenhouse producers
- Local manufacturing, short lead times, and responsive support
- Expertise in complex multi-span greenhouse installations
- Structures adapted to both organic certification and market demands
Thanks to Harnois’ team, the entire project, from engineering to installation, was executed with precision, allowing the farm to focus on what it does best: growing premium-quality herbs for Quebecers available 12 months a year.
Benefits for culinary herb operations
The local culinary herb producer, located in Saint-Norbert, allows them to produce all year long and reduces their environmental footprint (water recycling system, greenhouse insulation …).
Since the commissioning of their Luminosa greenhouse, Serres Gourma has reported:
- Greater production control and scheduling across all four seasons
- Improved herb quality, including aroma, uniformity, and shelf life
- More efficient labor and space use due to the large unobstructed interior
- Reduced disease pressure thanks to better climate management
- A more resilient and profitable operation, aligned with their growth strategy
This gutter-connecter greenhouse model offers a flexible and scalable option that supports the farm’s commercial objectives while preserving the unique character of their herbs.
