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 frosty. Opening the roof over the plants increases light intensity which can help control the growth habit, flowering and crop timing. It also reduces electricity 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 one or double level of flexible plastic glazing that runs the space of the greenhouse bay. A little gear electric motor rotates a shaft that winds the plastic on to it like a window shade. A light, second framework over the framework secures the plastic from bellowing out during windy climate. Starting and closing the roof can be either manual or automatic. Each side 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 standard vent hardware. Some have panels that hinge at the gutter and open 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 could be cup, polycarbonate or film plastic. Some manufacturers provide a movable gutter to collect rainwater when the roof is certainly partially open. Wind sensors ought to be set up to close the roof in stormy weather. Movable shade is generally installed with the open up roof design. It reduces the heat load by reflecting the suns rays back again out. The shade curtain should be of a porous style to allow heat to escape. 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 produces a watertight glazing. Based on the cropping program, bracing of the framework could be external cables mounted on deadmen, internal compression braces or trusses with cable X bracing. Flat roof styles are used where there is little rainfall or snow. A-roof designs shed the rainfall and snow to an interior gutter system. Designs which 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 handle up to 50,000 sq ft of roof Heating system is more difficult than in a conventional greenhouse due to the single layer plastic and better infiltration through gaps and cracks in the seals.
