Commercial Greenhouse Projects Completed across North America

At Harnois Greenhouses, every greenhouse project tells a story: that of a grower who has chosen to take control of their growing environment. Since 1965, we have been designing, manufacturing, and installing agricultural greenhouses tailored to the real-world demands of the terrain – from Quebec winters to the heat of Mexico. With 5000+ greenhouse projects completed across North America demonstrate the breadth of our expertise and the diversity of the turnkey solutions we deliver.
