Open roof greenhouses give a natural environment for plant growth when the outdoor climate would work and an artificial environment when it is too hot or cool. Opening the roof over the vegetation increases light intensity which can help control the growth habit, flowering and crop timing. It also reduces electricity costs as expensive lover cooling is not needed.
Several methods are accustomed to open the roof. Some manufacturers make a roof that opens by Gearbox For Greenhouse rolling up the solitary or double coating of flexible plastic-type glazing that runs the space of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic-type on to it like a window shade. A light, second framework over the framework secures the plastic-type from bellowing out during windy weather. Opening and closing the roof could 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 as they can be tightly closed during cold weather. Most designs use standard 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 about 85%. Most designs use rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic-type. Some manufacturers provide a movable gutter to gather rainwater when the roof can be partially open. Wind sensors should 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 out. The shade curtain should be of a porous style to allow heat to flee. In northern climates a power blanket can also be installed to lessen heat loss through the winter.
These structures contain a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Based on the cropping system, bracing of the structure could be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof styles are utilized where there is small rainfall or snow. A-roof designs shed the rain and snow to an internal gutter system. Styles which 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 leading edge of the curtain. One equipment 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 and higher infiltration through gaps and cracks in the seals.
