Retractable Roof Greenhouses (RRGH) and Retractable Shade Structures (RSS) are a new trend in the nursery industry that is pouring into the greenhouse industry. The ability to retract the roof and/or the side-walls, to allows maximum ventilation or sun-exposure, reduce the cost of environmental control in greenhouses in mild-winter climates while maintaining yields comparable to conventional greenhouses. RRGH and RSS are often also cheaper structures that offer the possibility to field growers to step up for more efficient, more effective production systems without unrealistic capital mobilization. The subject of this study is to evaluate vegetable crops (peppers & tomato) yield potential and physiological behavior in this kind of structures as a compromise between open field and greenhouses. Control strategies for the RRGH and training of the crop are also evaluated to find a more effective way to take advantage of the options offered by the structure itself. An economic evaluation is also conducted to verify the financial viability of the proposed production system.
