Commercial greenhouses for market gardeners and horticulturists
Welcome to Harnois, a Commercial greenhouse manufacturer based in Canada.
Designed with a team of engineers and agronomists, we have developed crop-driven greenhouse solutions. Our greenhouse structures maximize free light, create the optimal growing environment, mitigate extreme weather effects, protect crops from pests and diseases, and provide peace of mind for growers. Experience enhanced productivity and profitability with our innovative designs.
Minimalist Structure
Our greenhouse models feature oval tubes that provide the strongest structural integrity. This design allows for wider spacing between arches, resulting in increased light penetration.
Higher Air Volume
Our greenhouse models have a wider base and higher peak, providing a larger air volume. This leads to more stable temperatures, ultimately resulting in higher yields.
Profitability
Our greenhouse models offer growers peace of mind with an innovative design that ensures higher yields and better crop quality. Combined with energy savings, this leads to increased profitability.
