Why Consult one of our Greenhouse Experts Before Starting Your Project?

Every commercial greenhouse project starts with the right conversation. Whether you are a vegetable grower looking to extend your season, a flower producer scaling up, or a facility manager planning a large controlled environment agriculture (CEA) investment, a proper commercial greenhouse consultation is the single most important step before you commit to a structure.

Getting expert guidance from day one separates a project delivered on time and on budget from one riddled with costly surprises. At Harnois Greenhouses, consultation is not a sales call, it is the foundation of every successful project we have delivered across North America for over 60 years.

Why Book a Commercial Greenhouse Consultation Before You Build?

The decision to build a new commercial greenhouse structure is a major commitment, financially, operationally, and agronomically. Structures vary widely in design, materials, and performance. What works for a berry producer in Alberta will not work for an ornamental grower in Ontario or a cannabis cultivator in California.

Our team of engineers, agronomists, and project managers works directly with growers, from the first conversation to final installation, to ensure every structure performs exactly as planned. According to Agriculture and Agri-Food Canada, controlled environment agriculture operations consistently achieve 20 to 40% higher yields compared to open-field production. Those gains are only realized when the greenhouse is correctly sized, engineered, and sited from the outset. A poorly planned structure can undermine those advantages for years.

What Our Greenhouse Experts Evaluate for You

During your initial commercial greenhouse consultation, our specialists assess every variable that determines the right solution for your operation:

Your production goals. What crop are you growing? What square footage do you need to reach your target yield? Is this a four-season heated operation or a season-extension structure? Your answers guide the choice between:

A TunnelPro Plus high tunnel greenhouse for low-cost season extension
An Ovaltech freestanding greenhouse for independent multi-purpose production
A Luminosa gutter-connected greenhouse for large-scale commercial operations
A Vermax glass greenhouse for high-performance, near-zero energy growing environments

Your site and climate. Snow loads, wind speeds, and local geographic conditions drive structural requirements. Every Harnois greenhouse is engineered and manufactured in Canada, with stamped engineering plans compliant with North American building codes. A site visit or remote analysis can be arranged to confirm structural compatibility before any commitment is made.

Your budget and timeline. We frame a realistic proposal aligned with your investment capacity and project schedule. Our typical delivery process runs 8 to 15 weeks depending on project complexity, from discovery and evaluation through engineering, manufacturing, and installation on your site.

A True Turnkey Partner — From Design to Delivery

What sets Harnois Greenhouses apart is our ability to manage every phase of your project in-house. No juggling multiple subcontractors. No diffused accountability.

Our integrated team handles:

Discovery and needs assessment — crop type, production goals, site constraints
Engineering — stamped structural plans compliant with local building codes
Manufacturing — fabricated at our Quebec facility using Canadian-grade materials
Installation — our own crews, not third-party contractors

This vertical approach ensures complete consistency between what is promised during your consultation and what is delivered on the ground. It also allows us to transfer innovations developed for our most advanced structures, such as the AI-driven microclimatic control systems in the Vermax, across our full product line, benefiting every grower regardless of budget.

As Andrew Plantinga, Facility Manager at Van Belle Finished Plants, put it: “With Harnois, the certainty was there.” That certainty starts with a thorough consultation, not a generic quote.
