By reimagining established concepts, we create growing systems with structures and technologies that anticipate tomorrow’s needs. Our iconic innovations, such as the Gothic profile, embody this mission every day. Each of our greenhouses maximizes natural light, creating ideal conditions for growth while offering greater predictability. And with Canada’s first glass greenhouse, we combine carbon-neutral technologies with adaptability, offering more than just a structure—a sustainable vision for agriculture.

ABOUT

Greenhouses for Commercial Growers

Designed specifically for commercial growers, our greenhouses combine structural strength, light optimization, and disease-reducing technology to help you achieve better yield, higher quality, and greater profitability — season after season.

With over 60 years of experience and tens of thousands of installations across North America, we’ve earned the trust of professional growers in vegetables, ornamentals, berries, and nursery production. Our four proven greenhouse models offer the flexibility, performance, and longevity required to support modern horticulture — even in the harshest climates.
