Open roof greenhouses give a environment for plant growth when the outdoor weather is suitable and an artificial environment when it is too hot or cold. Opening the roof over the plant life increases light intensity which can help to control the growth 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 up the roof. Some manufacturers make a roof that opens by rolling up the single or double coating of flexible plastic-type glazing that runs the distance of the greenhouse bay. A small gear motor rotates a shaft that winds the plastic on to it like a window shade. A light, second framework over the structure secures the plastic from bellowing out during windy weather conditions. Starting and closing the roof can be either manual or automatic. Each part of the roof could be controlled independently for versatility 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 upward. Opening is almost 100%. Others have panels that are hinged at the ridge and one gutter and slide sideways on teflon bearings. Opening is approximately 85%. Most designs use rubber gasketing to seal the joints. Glazing could be cup, polycarbonate or film plastic-type. Some manufacturers give a movable gutter to collect rainwater when the roof is usually partially open up. Wind sensors ought to be set up to close the roof in stormy weather. Movable shade is generally installed with the open up roof design. It decreases the heat load by reflecting the suns rays back again out. The color curtain should be of a porous style to allow heat to flee. In northern climates an energy blanket may also be installed to reduce heat loss during the winter.
These structures consist of a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. With respect to the cropping system, bracing of the structure can be external cables attached to deadmen, internal compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is little rainfall or snow. A-roof styles shed the rainfall and snow to an internal gutter system. Styles that may carry up to 35 lb/sq ft snow load and 100 mph wind loads are available. The roof opens in sections by shifting the industry leading of the curtain. One gear motor will manage up to 50,000 sq ft of roof Heating is more challenging than in a conventional greenhouse because of the single layer plastic and higher infiltration through gaps and cracks in the seals.
