At Harnois Greenhouses, we offer a complete range of commercial greenhouse equipment engineered to help professional growers increase yields, reduce operating costs, and maintain optimal growing conditions throughout the year. Whether you are setting up a new facility or upgrading an existing one, our technology solutions adapt to your operation — from the essentials to full greenhouse automation.
Every piece of equipment we supply integrates directly with our commercial greenhouse structures, giving you a single, trusted source for your entire growing environment.
Equip Your Greenhouse for Maximum Performance
Choosing the right greenhouse equipment is not a catalogue decision — it is a production decision. Poorly matched systems waste energy, create inconsistent growing conditions, and reduce crop quality. At Harnois, our agronomists and project advisors work with you to select and configure equipment that matches your crop type, climate zone, and growth plan.
Our commercial greenhouse equipment programs are built around nine core categories, each available individually or as part of a complete turnkey package.
Advantages of Our Greenhouse Technologies:
- Cost savings derived from optimized operations.
- Optimal environmental conditions for healthier crops.
- Disease prevention
- Increased production and improved crop quality
- Greenhouse management with software platforms
- Enhanced control and prevention
Our Greenhouse Equipment Categories
Covering — Poly Film, Polycarbonate & Glass
Your covering choice directly affects light transmission, insulation value, and long-term operating costs. We supply double polyethylene film, polycarbonate panels (PCSS), and glass — each suited to different crops and climates. Explore our greenhouse covering options.
Climate Control — Heating, Cooling & Sensors
Greenhouse climate control is the foundation of consistent crop performance. Our systems include heating circuits, evaporative cooling, CO₂ enrichment, humidity management, and sensor networks that monitor your growing environment in real time — automatically adjusting conditions around the clock. Learn more about our climate control systems.
Water & Irrigation Systems
From drip and boom irrigation to recirculating fertigation systems, our greenhouse irrigation solutions deliver the right amount of water and nutrients directly to the root zone. Our Aquaboom robotic watering system further reduces labour while improving irrigation precision for large operations.
Ventilation — Natural & Mechanical
Proper airflow removes excess heat and humidity, prevents disease pressure, and maintains a steady supply of fresh CO₂ for your crops. We offer roof vents, side roll-up panels, and mechanical fan-and-pad cooling for every structure type. See our greenhouse ventilation systems.
Screens — Energy, Blackout & Insect
Thermal energy screens can reduce heating costs by 30–50%. Blackout screens enable precise photoperiod control for light-sensitive crops. Insect exclusion nets reduce pest pressure without chemicals. Browse our full range of greenhouse screens.
Digital Greenhouse — Automation & Control
Our digital greenhouse solutions integrate climate, irrigation, lighting, and screening into a single, connected control platform. Using Priva, Hoogendoorn, or our proprietary Connext interface, you gain real-time monitoring, alarm management, and remote access from any device — the backbone of a fully automated commercial operation.
Growing Systems — Hydroponics, NFT & Soilless
Soilless production delivers higher yields per square foot, better disease resistance, and more efficient use of water and nutrients. Our growing systems include substrate culture, NFT channels, and deep water culture setups designed for vegetables, herbs, strawberries, and more.
Lighting — HPS & LED Grow Lights
Supplemental lighting extends your growing season and increases yields on light-sensitive crops. We supply both High-Pressure Sodium (HPS) and LED grow light systems. LED fixtures deliver 40–60% energy savings compared to HPS and are now the preferred choice for most new commercial installations. Explore our greenhouse lighting options.
Growing Benches — Elevated & Flood Bench Systems
Greenhouse growing benches increase your usable floor area, improve worker ergonomics, and in flood bench configurations, enable precise sub-irrigation with water recirculation. Moveable rolling bench systems can bring your usable growing space up to 90% of total floor area.
One Supplier. Complete Integration.
Harnois Greenhouses is one of the few suppliers in North America able to provide both the structure and the full equipment package from a single source. This eliminates compatibility issues, simplifies procurement, and ensures every system works as designed from day one.
Our team of engineers, agronomists, and project managers supports you through equipment selection, installation, commissioning, and ongoing technical support — the same commitment we bring to every greenhouse project we complete.
