20'x24' Semi-Gable greenhouse frames have taller sidewalls that reach a higher peak than the Quonset greenhouse frame type. The high pitch allows for better snow shedding and provides the largest interior volume of space per square foot. Semi-Gable greenhouse frames provide easy access, the most usable growing space, and can withstand snow.
