Open roof greenhouses provide a environment for plant growth when the outdoor climate would work and an artificial environment when it's too hot or frosty. Starting the roof over the plants increases light intensity that may help to control the growth habit, flowering and crop timing. In addition, it reduces electricity costs as expensive lover cooling isn't needed.
Several methods are used to open up the roof. Some manufacturers make a roof that opens by rolling up the solitary or double coating of flexible plastic glazing that runs the distance of the greenhouse bay. A small gear motor rotates a shaft that winds the plastic material on to it like a window color. A light, second framework over the framework secures the plastic-type material from bellowing out during windy weather conditions. Opening and closing the roof can 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 shut during cold weather. Most designs use regular vent hardware. Some have panels that hinge at the gutter and open up upward. Opening is almost 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 cup, polycarbonate or film plastic-type material. Some manufacturers provide a movable gutter to collect 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 frequently installed with the open roof design. It decreases the heat load by reflecting the suns rays back again out. The shade Gear Motor For Greenhouse curtain ought to be of a porous design to allow heat to flee. In northern climates an energy blanket can also be installed to reduce heat loss through the winter.
These structures consist of a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Based on the cropping system, bracing of the framework could be external cables attached to deadmen, internal compression braces or trusses with cable X bracing. Flat roof designs are used where there is small rainfall or snow. A-roof designs shed the rain and snow to an internal gutter system. Designs that may 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 leading edge of the curtain. One gear motor will handle up to 50,000 sq ft of roof Heating system is more difficult than in a typical greenhouse because of the single layer plastic and higher infiltration through gaps and cracks in the seals.
