Open roof greenhouses provide a natural environment for plant growth when the outdoor weather is suitable and an artificial environment when it is too hot or frosty. Opening the roof over the plant life increases light intensity which can help control the growth habit, flowering and crop timing. It also Gear Motor For Greenhouse reduces electricity costs as expensive fan cooling isn’t needed.
Several methods are used to open up the roof. Some producers make a roof that opens by rolling up the solitary or double layer of flexible plastic-type glazing that runs the length of the greenhouse bay. A little gear electric motor rotates a shaft that winds the plastic material on to it just like a window shade. A light, second framework over the framework secures the plastic material from bellowing out during windy weather conditions. Opening and closing the roof can be either manual or automatic. Each side of the roof can be controlled independently for flexibility in cooling.
Folding roof greenhouses work very well in snowy climates as 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 make use of rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic material. Some manufacturers give a movable gutter to gather rainwater when the roof is partially open. Wind sensors should be set up to close the roof in stormy weather. Movable shade is frequently installed with the open up 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 may also be installed to reduce heat loss during the winter.
These structures consist of a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. According to the cropping program, bracing of the framework could be external cables attached to deadmen, internal compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is small rainfall or snow. A-roof styles shed the rainfall 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 gear motor will deal with up to 50,000 sq ft of roof Heating is more difficult than in a typical greenhouse due to the single layer plastic-type and higher infiltration through gaps and cracks in the seals.
