Open roof greenhouses Gear Motor For Greenhouse provide a natural environment for plant growth when the outdoor weather is suitable and an artificial environment when it’s too hot or cool. Opening the roof over the vegetation increases light intensity that may help to control the development habit, flowering and crop timing. In addition, it reduces electrical power costs as expensive lover cooling is not needed.
Several methods are accustomed to open the roof. Some manufacturers make a roof that opens by rolling up the one or double layer of flexible plastic-type material glazing that runs the space of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic-type material on to it such as a window shade. A light, second framework over the framework secures the plastic from bellowing out during windy weather conditions. Opening and closing the roof can be either manual or automatic. Each side of the roof can be managed independently for versatility in cooling.
Folding roof greenhouses work well in snowy climates as they can be tightly closed during winter. Most designs use regular vent hardware. Some have panels that hinge at the gutter and open upward. Opening is nearly 100%. Others have 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-type material. Some manufacturers give a movable gutter to gather rainwater when the roof is certainly 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 reduces heat load by reflecting the suns rays back again out. The color curtain should be of a porous style to allow heat to escape. In northern climates an energy blanket can also be installed to lessen heat loss during the winter.
These structures contain a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Based on the cropping program, bracing of the framework could be external cables mounted on deadmen, internal compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is little rainfall or snow. A-roof designs shed the rainfall and snow to an interior gutter system. Designs which will 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 gear motor will manage up to 50,000 sq ft of roof Heating is more difficult than in a typical greenhouse due to the single layer plastic-type and better infiltration through gaps and cracks in the seals.
