Open roof greenhouses provide a natural environment for plant growth when the outdoor weather conditions would work and an artificial environment when it is too hot or cool. Starting the roof over the plants increases light intensity which can help control the development habit, flowering and crop timing. In addition, it reduces electricity costs as expensive enthusiast cooling is not needed.
Several methods are used to open up the roof. Some manufacturers make a roof that opens by rolling up the one or double coating of flexible plastic-type 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 Gearbox For Greenhouse framework over the framework secures the plastic material from bellowing out during windy weather. Opening and closing the roof can be either manual or automatic. Each aspect of the roof could be controlled independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates because they can be tightly shut during cold weather. Most designs use standard vent hardware. Some possess panels that hinge at the gutter and open 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 about 85%. Most designs make use of rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic. Some manufacturers provide a movable gutter to gather rainwater when the roof can be partially open up. Wind sensors ought to be set up 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 color curtain ought to be of a porous design to allow heat to flee. In northern climates an energy blanket may also be installed to lessen heat loss during the winter.
These structures consist of a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Depending on the cropping program, bracing of the framework can be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is little rainfall or snow. A-roof styles shed the rain and snow to an interior gutter system. Designs that will carry up to 35 lb/sq ft snow load and 100 mph wind loads are available. The roof opens in sections by moving the industry leading of the curtain. One gear motor will manage up to 50,000 sq ft of roof Heating system is more difficult than in a typical greenhouse due to the single layer plastic material and higher infiltration through gaps and cracks in the seals.
