What Rough Brothers Inc does

Rough Brothers Inc, now operating under the Prospiant brand, is a privately held U.S. greenhouse design, manufacturing, and construction firm headquartered in Cincinnati, Ohio, with a second operational location in Kingsville, Ontario. The company traces its origins to 1894 and self-describes as the largest U.S. provider of complete commercial greenhouses, cultivation structures, and growing equipment. Its core offering is full-stack controlled-environment agriculture (CEA) infrastructure, organized around four capabilities — Design, Build, Integrate, and Operate — and a broad product portfolio spanning multiple proprietary greenhouse structure lines (Venlo, Dual Atrium, Vail A-Frame, Open Roof, Grand Teton, Windjammer, Columbine, Poly Arch, institutional, and custom variants), climate and irrigation equipment (HVACD, heating, ventilation, shade/energy curtains, fertigation, lighting, benches, doors), glazing materials, and auxiliary structures including steel utility buildings and specialty glass enclosures.

The company serves three primary end-markets: Fruits and Vegetables, Flowers and Retail, and Research and Education, with additional exposure to the cannabis vertical through light deprivation and blackout systems. GTM appears to be a direct, project-based B2B model selling capital equipment and integrated systems to commercial growers, retail garden centers, and institutional buyers; specific reference customers named in source imagery include Ebert's Garden Center, Pleasant View Gardens, and Red Oak. Revenue mechanics are not disclosed, but the business model combines one-time structural project revenue with follow-on equipment, integration, and (potentially) aftermarket service. Adjacent revenue is generated through a powder coating service line (powdercoating.prospiant.com) and an emerging portfolio of non-horticulture glazed structures — pool enclosures, car-wash enclosures, hotel canopies, and BIPV solar shade canopies — that leverage existing structural glazing IP.

Rough Brothers/Prospiant is owned by no disclosed institutional investor; the company is privately held with a workforce of 51–100 employees. Two historical founders, Robert T. Rough and Earl M. Rough, are documented, but no current management team, board, or ownership structure is provided in the source data.
