Multi-bay steel construction creates one continuous, column-free growing space with over 90% land utilization — no wasted side walls, no fragmented bays. Top film covering pairs with flexible side-wall options (film, polycarbonate, or color steel), and the structure supports a full suite of automated systems from ventilation and shading to heating, supplemental lighting, and fertigation.
