The MX3 Greenhouse Structure is an option that allows for the best of both worlds which is an economic double poly structure with natural ventilation capabilities. By opening every third peak you minimize mechanical components without losing the option to use passive cooling techniques to reduce operational costs. The structure is made of aluminum extrusions and a hot dipped galvanized steel substructure.
