Open roof greenhouses give a natural environment for plant growth when the outdoor weather would work and an artificial environment when it is too hot or cold. Starting the roof over the plants increases light intensity which can help to control the growth habit, flowering and crop timing. In addition, it reduces electrical power costs as expensive lover cooling isn’t needed.
Several methods are accustomed to open the roof. Some producers make a roof that opens by rolling up the single or double level of flexible plastic glazing that runs the length of the greenhouse bay. A small gear electric motor rotates a shaft that winds the plastic material on to it 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 side of the roof can be managed independently for versatility in cooling.
Folding roof greenhouses work very well in snowy climates as they can be tightly shut during cold weather. Most designs use regular vent hardware. Some have panels that hinge at the Gearbox For Greenhouse 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 use rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic material. Some manufacturers provide a movable gutter to collect rainwater when the roof is certainly partially open. Wind sensors ought to be installed to close the roof in stormy climate. 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 escape. In northern climates an energy blanket can also be installed to reduce heat loss during the winter.
These structures contain a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Based on the cropping system, bracing of the framework can 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 rainfall and snow to an internal gutter system. Designs that will carry up to 35 lb/sq ft snow load and 100 mph wind loads can be found. 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 challenging than in a conventional greenhouse due to the single layer plastic material and better infiltration through gaps and cracks in the seals.
