GrowerTalks Senior Editor Bill Calkins talks to Corenthin (Felix) Chassouant, the VP of Sales—Poly Greenhouses at Harnois Industries, about the company’s new TunnelPro Plus high tunnel greenhouse.
Felix explains the reasons Harnois developed the TunnelPro Plus structure designed specifically for modern, extreme climate conditions while also taking into account agronomics and optimal growing conditions for a range of crops traditionally done in open-field. This new greenhouse system is extremely durable and economical with the height, width and structural specifications to create a uniform climate for plants and production teams. TunnelPro Plus is scalable for future expansion and large enough to allow for machinery and automation and can accommodate a range of different poly coverings and structural additions like hanging basket lines to maximize production. As Felix explains, it’s a truly innovative upgrade to traditional shade houses and high tunnels.
