Open roof greenhouses give a environment for plant growth when the outdoor climate is suitable and an artificial environment when it is too hot or chilly. Starting the roof 
over the plants increases light intensity which can help to control the development habit, flowering and crop timing. In addition, it reduces electricity costs as expensive enthusiast cooling is not needed.
Several methods are used to open up the roof. Some manufacturers make a roof that opens by rolling up the solitary or double level of flexible plastic material glazing that runs the distance of the greenhouse bay. A little gear motor rotates a shaft that winds the plastic-type on to it like a Gearbox For Greenhouse window shade. A light, second framework over the framework secures the plastic-type material from bellowing out during windy weather. Starting and closing the roof could 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 winter. Most designs use standard vent hardware. Some possess 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 approximately 85%. Most designs use rubber gasketing to seal the joints. Glazing can be cup, polycarbonate or film plastic-type material. Some manufacturers give a movable gutter to collect rainwater when the roof is definitely partially open. Wind sensors ought to be set up to close the roof in stormy climate. Movable shade is generally installed with the open roof design. It reduces the heat load by reflecting the suns rays back again out. The color curtain ought to be of a porous style to allow heat to flee. In northern climates an energy blanket may also be installed to lessen heat loss through the winter.
These structures consist of a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. According to the cropping program, bracing of the structure could 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 interior gutter system. Styles 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 moving the leading edge of the curtain. One equipment motor will handle up to 50,000 sq ft of roof Heating is more challenging than in a conventional greenhouse because of the single layer plastic material and higher infiltration through gaps and cracks in the seals.
