Tailored to the needs of fruit and vegetable producers
Fruit and vegetable cultivation is essential for ensuring local food security. As a cornerstone of nutrition, fruits and vegetables provide dietary diversity and contribute to balanced diets. Some fruits and vegetables have the advantage of growing vertically, making them particularly suited to efficient produce greenhouses.
Thanks to produce greenhouse technologies, fruit and vegetable farming has become highly optimized, reducing resource usage, increasing yields, and minimizing pesticide use.
These advantages are elevated in greenhouses, enabling the production of diverse, fresh harvests that meet nutritional needs.
Produce Greenhouses - Your Benefits
Predictable Yields
A greenhouse creates optimal growing conditions by controlling essential factors like temperature, humidity, and light, improving crop yields and ensuring more consistent and higher-quality harvests.
Extended Growing Season
Produce greenhouses allow you to start production earlier and extend it into the fall, providing a greater market presence and the ability to supply fresh vegetables year-round.
Reduced Environmental Footprint
Greenhouses optimize resource use, such as water and nutrients, reducing costs and minimizing the environmental impact of your crops.
Protection Against Weather Extremes
Greenhouses protect crops from adverse weather and sudden climate variations, ensuring more stable production and resilience to climate change.

4 Types of Commercial Produce Greenhouses That Maximize Crop
At Harnois Greenhouses, we specialize in innovative, durable structures that help growers scale operations efficiently and sustainably. Choosing the right type of commercial produce greenhouse is essential for optimizing yield, improving climate control, and reducing operational costs. Here’s a look at the four main greenhouse models we offer, each designed to support different needs in professional produce farming.
1. High Tunnel Greenhouses
High tunnels are a simple yet highly effective solution for extending your growing season. These unheated structures protect crops from wind, rain, and temperature fluctuations while promoting early planting and late harvests. High tunnels are ideal for small to medium-sized growers focused on field-grown vegetables and leafy greens. They’re easy to install, cost-effective, and customizable to your layout needs.
2. Freestanding Greenhouses
Freestanding greenhouses are single, stand-alone structures that provide growers with full control over their internal climate. These greenhouses are perfect for crop separation and targeted cultivation—whether for different produce varieties or organic certification zones. They can be engineered for all climates and scaled to fit various levels of production, making them a go-to for flexible, independent growing.
3. Gutter-Connected Greenhouses
Designed for large-scale, high-efficiency growing, gutter-connected greenhouses link multiple bays under one roof. These structures are ideal for maximizing usable space and minimizing energy costs. They support advanced environmental controls, ventilation, and irrigation systems—making them excellent for hydroponics, vertical farming, and diversified produce greenhouse systems.
4. Glass Greenhouses
If you’re aiming for high light transmission and long-term durability, glass greenhouses are the premium choice. They offer superior insulation and a professional look, ideal for both commercial agriculture and demonstration projects. Their precision engineering makes them especially suitable for high-value crops like tomatoes, peppers, and herbs.
Whether you’re expanding your farm or launching a new growing facility, Harnois offers proven solutions in commercial greenhouse structures built for lasting performance. Each model is designed with efficiency, sustainability, and crop success in mind.
