Open roof greenhouses give a environment for plant growth when the outdoor climate would work and an artificial environment when it’s 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 enthusiast cooling is not needed.
Several methods are used to open up the roof. Some producers make a roof that opens by rolling up the single or double level of flexible plastic-type material glazing that runs the length of the greenhouse bay. A little gear electric motor rotates a shaft that winds the plastic-type 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 versatility 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 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 can be glass, polycarbonate or film Gear Motor For Greenhouse plastic material. Some manufacturers give a movable gutter to gather rainwater when the roof can be partially open. 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 the heat load by reflecting the suns rays back out. The shade curtain should be of a porous design to allow heat to flee. In northern climates a power blanket can also be installed to lessen heat loss through the winter.
These structures contain a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Depending on the cropping system, bracing of the framework could be external cables mounted on deadmen, internal compression braces or trusses with cable X bracing. Flat roof designs are used where there is little rain or snow. A-roof designs shed the rain and snow to an interior gutter system. Styles 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 equipment motor will deal with up to 50,000 sq ft of roof Heating is more challenging than in a conventional greenhouse because of the single layer plastic and higher infiltration through gaps and cracks in the seals.
