Product Brochures & Catalogs
Commercial Greenhouse Brochures
Our main commercial greenhouse brochure covers the entire Harnois product line, from high tunnels to advanced glass structures. Inside, you will find frame options, cladding materials, ventilation systems, standard dimensions, and available equipment packages. This catalog is the starting point for any grower, architect, or project manager evaluating a new greenhouse facility.
The Ovaltech is also available with optional webbed trusses for hanging baskets, elevated growing benches, and full irrigation systems, making it a complete turnkey solution for floriculture, nurseries, and produce operations of any scale.
The Luminosa is particularly well-suited for year-round tomato, cucumber, and pepper production. Its gutter-connected design maximizes usable floor space and allows phased expansion, adding bays as your operation grows without interrupting production.
The TunnelPro Plus is also available with side roll-up ventilation, full-width roll-up doors opening up to 13', and elevated growing benches that increase harvest speed by up to 40% compared to ground-level production, a proven advantage for soft fruit growers.
