Open roof greenhouses provide a natural environment for plant growth when the outdoor climate would work and an artificial environment when it is too hot or cold. Starting the roof over the vegetation increases light intensity which can help to control the development habit, flowering and crop timing. In addition, it reduces electrical power costs as expensive fan cooling is not needed.
Several methods are used to open the roof. Some manufacturers make a roof that opens by rolling up the one or double layer of flexible plastic material glazing that operates the length of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic on to it like a window shade. A light, second framework over the framework secures the plastic from bellowing out during windy weather conditions. Starting and closing the roof can be either manual or automatic. Each side of the roof could be controlled independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates because they can be tightly closed during cold weather. Most designs use standard vent hardware. Some have panels that hinge at the gutter and open up upward. Opening is nearly 100%. Others possess panels that are hinged at the ridge and one gutter and slide sideways on teflon bearings. Opening is about 85%. Most designs make use of rubber gasketing to seal the joints. Glazing can be cup, polycarbonate or film plastic material. Some manufacturers give a movable gutter to collect rainwater when the roof is usually partially open. Wind sensors should be installed to close the roof in stormy climate. Movable shade is generally installed with the open up roof design. It decreases heat load by reflecting the suns rays back out. The shade curtain should be of a porous style to allow heat to flee. In northern climates a power blanket may also be installed to reduce heat loss through the winter.
These structures contain a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Depending on the cropping system, bracing of the structure could be external cables mounted on deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is little rain or snow. A-roof designs shed the rainfall and snow to an internal gutter system. Designs that may carry up to 35 lb/sq ft snow load and 100 mph wind loads can be found. The roof opens in sections by shifting the leading edge of the curtain. One equipment motor will manage up to 50,000 sq ft of roof Heating is more challenging than in a typical greenhouse due to the single layer plastic-type material and higher infiltration through gaps and cracks in the seals.
