Open roof greenhouses give a environment for plant growth when the outdoor climate would work and an artificial environment when it is too hot or cold. Starting the roof over the vegetation increases light intensity that may help control the development habit, flowering and crop timing. In addition, it reduces electricity costs as expensive lover cooling isn’t needed.
Several methods are used to open the roof. Some manufacturers make a roof that opens by rolling up the one or double level of flexible plastic-type material glazing that operates the length of the greenhouse bay. A small gear motor rotates a shaft that winds the plastic-type material on to it just like a window color. A light, second framework over the structure secures the plastic-type from bellowing out during windy weather conditions. Starting and closing the roof could be either manual or automatic. Each part of the roof could be controlled independently for flexibility in cooling.
Folding roof greenhouses work very well in snowy climates as they can be tightly closed during winter. Most designs use standard vent hardware. Some possess 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 approximately 85%. Most designs make use of rubber gasketing to seal the joints. Glazing could be glass, polycarbonate or film plastic-type. Some manufacturers provide a movable gutter to gather rainwater when the roof is partially open. Wind sensors should be installed 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 should be of a porous design to allow heat to flee. In northern climates a power blanket may 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 produces a watertight glazing. With respect to 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 styles 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 deal with up to 50,000 sq ft of roof Heating system is more difficult than in a conventional greenhouse because of the single layer plastic-type material and higher infiltration through gaps and cracks in the seals.
