Open roof greenhouses provide a natural environment for plant growth when the outdoor weather conditions would work and an artificial environment when it is too hot or chilly. Gearbox For Greenhouse Opening the roof over the plants increases light intensity which can help control the growth habit, flowering and crop timing. In addition, it reduces electricity costs as expensive enthusiast cooling is not needed.
Several methods are accustomed to open up the roof. Some producers make a roof that opens by rolling up the single or double level of flexible plastic material glazing that operates the length of the greenhouse bay. A small gear motor rotates a shaft that winds the plastic material on to it such as a window shade. A light, second framework over the structure secures the plastic from 
bellowing out during windy climate. Starting and closing the roof could be either manual or automatic. Each part of the roof can be controlled independently for flexibility in cooling.
Folding roof greenhouses work very well in snowy climates because they can be tightly closed during cold weather. Most designs use regular vent hardware. Some possess panels that hinge at the gutter and open up upward. Opening is almost 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 provide a movable gutter to gather rainwater when the roof is partially open up. Wind sensors should be set up to close the roof in stormy weather. Movable shade is frequently installed with the open roof design. It decreases the heat load by reflecting the suns rays back out. The color curtain should be of a porous design to allow heat to escape. In northern climates an energy blanket can also be installed to lessen heat loss during the winter.
These structures consist of a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. According to the cropping system, bracing of the framework 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 rain or snow. A-roof styles shed the rain 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 manage up to 50,000 sq ft of roof Heating system is more difficult than in a typical greenhouse due to the single layer plastic-type and greater infiltration through gaps and cracks in the seals.
