Greenhouse coverings

Your greenhouse covering matters as much as its structure. It determines how much light reaches your crops, how heat and humidity are managed inside, and how long your investment lasts before it needs replacing. At Harnois, every covering is chosen and installed to get the most out of your structure, whether you go with a high-performance polyethylene like EVO2 AC, offering up to 90-91% light transmission, a polycarbonate panel, or a Vermax glass greenhouse.

The right choice depends on your crop, your budget, and your long-term goals.
