Open roof greenhouses give a natural environment for plant growth when the outdoor weather conditions is suitable and an artificial environment when it is too hot or cold. Starting the roof over the plants increases light intensity which can help control the growth habit, flowering and crop timing. It also reduces electrical power costs as expensive enthusiast cooling isn’t needed.
Several methods are accustomed to open the roof. Some manufacturers make a roof that opens by rolling up the one or double layer of flexible plastic-type glazing that runs the space of the greenhouse bay. A little gear motor rotates a shaft that winds the plastic on to it such as a window color. A light, second framework over the structure secures the plastic from bellowing out during windy climate. Gearbox For Greenhouse Opening and closing the roof can be either manual or automatic. Each part of the roof can be managed independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates as they can be tightly shut during winter. Most designs use standard 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 about 85%. Most designs make use of rubber gasketing to seal the joints. Glazing could be cup, polycarbonate or film plastic material. Some manufacturers provide a movable gutter to collect rainwater when the roof is usually partially open. Wind sensors should be set up to close the roof in stormy weather. Movable shade is generally installed with the open 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 a power blanket may also be installed to reduce heat loss during the winter.
These structures contain a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Based on the cropping program, bracing of the structure can be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is small rain or snow. A-roof styles shed the rain and snow to an interior gutter system. Designs that may carry up to 35 lb/sq ft snow load and 100 mph wind loads are available. The roof opens in sections by moving the leading edge of the curtain. One equipment motor will manage up to 50,000 sq ft of roof Heating system is more difficult than in a typical greenhouse because of the single layer plastic-type material and greater infiltration through gaps and cracks in the seals.
