Open roof greenhouses provide a natural environment for plant growth when the outdoor climate would work and an artificial environment when it’s too hot or frosty. Opening the roof over the vegetation increases light intensity that may help to control the development habit, flowering and crop timing. It also reduces electrical power costs as expensive fan 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 layer of flexible plastic glazing that runs the length of the greenhouse bay. A little gear electric motor rotates a shaft that winds the plastic-type material on to it just like a window color. A light, second framework over the framework secures the plastic from bellowing out during windy weather. Opening and closing the roof could be either manual or automatic. Each part of the roof can be managed Gear Motor For Greenhouse 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 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 make use of 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 ought to be installed to close the roof in stormy weather. Movable shade is frequently installed with the open roof design. It reduces the heat load by reflecting the suns rays back again out. The shade curtain ought to be of a porous style to allow heat to flee. In northern climates a power blanket can 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 creates a watertight glazing. With respect to the cropping program, bracing of the framework can be external cables mounted on deadmen, inner compression braces or trusses with cable X bracing. Flat roof styles are utilized where there is little rain or snow. A-roof designs shed the rain and snow to an internal gutter system. Designs that will carry up to 35 lb/sq ft snow load and 100 mph wind loads are available. The roof opens in sections by shifting the leading edge of the curtain. One gear motor will handle up to 50,000 sq ft of roof Heating is more difficult than in a conventional greenhouse because of the single layer plastic and better infiltration through gaps and cracks in the seals.
