DeCloet Greenhouse Manufacturing

What DeCloet Greenhouse Manufacturing does

DeCloet Greenhouse Manufacturing Ltd. is a Canadian designer and manufacturer of commercial greenhouse structures, founded in 1986 and headquartered in Simcoe, Ontario. The company serves production growers, nurseries, and retail garden centers across Canada and the United States. Its core product portfolio spans gutter-connect structures (18', 21', 24' widths), the multi-functional Grow Max series (30' and 40'), freestanding greenhouses across multiple series (Growers Choice, Cropmaster, Sunmaster, Norfolk), European-style Venlo glass greenhouses, garden and retail centers, special-purpose non-growing structures, and schools/institutional models. Differentiated engineering features include exclusive oval bows on 4 ft and 6 ft centers, an exclusive 11-gauge heavy gutter, post-manufacture galvanization, and proprietary 2 1/3 inch roll-up tubing with built-in wirelock.

DeCloet operates a vertically integrated offering around the greenhouse shell: bench systems (stationary and rolling, aluminum rails on galvanized frames), ventilation systems (forced air with fans/shutters/cooling pads plus passive vents), energy curtains for light deprivation and solar screening, and greenhouse control systems integrated with leading third-party suppliers (Wadsworth Step 50A/Step 500/Envirostep, Bartlett Instruments, Priva, Link 4, Argus). Installation, heating, and after-sale service are bundled into the project delivery model.

The business model is project-driven enterprise field sales: quotes are custom-built per customer, with a Derotto Leasing partnership providing equipment financing for Canadian and U.S. customers. Go-to-market is direct sales targeting commercial growers and nurseries, supported by trade-show presence (notably MANTS) and a website that functions as a product catalog and news outlet for reference projects such as Walters Gardens, the University of Guelph, and the award-winning Hope Blooms Community Greenhouse. Revenue is not publicly disclosed; channel and segment breadth across growers, retail, and institutional customers indicate a horizontally diversified customer mix within North American horticulture.
