Open roof greenhouses provide a natural environment for plant growth when the outdoor weather conditions is suitable and an artificial environment when it is too hot or chilly. Starting the roof over the vegetation increases light intensity that may help to control the development habit, flowering and crop timing. It also reduces electricity 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 one or double level of flexible plastic-type glazing that operates the space of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic material on to it such as a window color. A light, second framework over the framework secures the plastic-type from bellowing out during windy weather. Starting and closing the roof can be either manual or automatic. Each side of the roof could be managed 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 about 85%. Most designs use rubber gasketing to seal the joints. Glazing could be cup, polycarbonate or film plastic-type material. Some manufacturers give a movable gutter to gather rainwater when the roof is partially open up. Wind sensors ought to be set up to close the roof in stormy weather. Movable shade is frequently installed with the open up roof design. It decreases the heat load by reflecting the suns rays back out. The shade curtain should be of a porous style to allow heat to escape. In northern climates an energy blanket may also be installed to reduce 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. With respect to the cropping system, bracing of the structure could be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are used where there is little rain or snow. A-roof styles shed the rainfall and snow to an interior gutter system. Styles 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 moving the leading edge of the curtain. One gear motor will handle up to 50,000 sq ft of roof Heating Gear Motor For Greenhouse system is more challenging than in a typical greenhouse due to the single layer plastic and greater infiltration through gaps and cracks in the seals.
