Projects Tailored to All Scales, with Unmatched Commitment
At Harnois Greenhouses, we have the capability to deliver greenhouse projects of any scale, from a single individual greenhouse to large-scale installations. Regardless of the project’s size, we bring the same energy and dedication to ensure innovative and sustainable solutions that address the current challenges of agriculture.
Climate change is a global concern, and we contribute to this cause by integrating modern and efficient agricultural practices into our projects. Our greenhouses combine cutting-edge technology, optimized water management, and integrated pest control, offering a model of efficiency, resilience, and environmental responsibility.
Through advancements such as climate control systems and automation, we maximize production while minimizing carbon footprints. Our closed-loop water management systems reduce waste and optimize resource use, making our greenhouses particularly effective even in the face of climate challenges.
Every greenhouse project also contributes to the local economy. Controlled environments bring stability and predictability to yields, enhancing investment attractiveness and creating direct and indirect jobs. By providing comprehensive support—from training local teams to sourcing materials—we actively support economic growth in the regions we serve.
At Harnois, we take pride in supporting every grower, big or small, in building a more efficient and sustainable agricultural future.
