Open roof greenhouses give a natural environment for plant growth when the outdoor weather would work and an artificial environment when it is too hot or cold. Opening the roof over the plant life increases light intensity which can help to control the growth 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 single or double layer of flexible plastic-type glazing that runs the length of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic-type on to it such as a window shade. 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 managed independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates as 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 Gear Motor For Greenhouse joints. Glazing could be cup, polycarbonate or film plastic-type. Some manufacturers provide a movable gutter to collect rainwater when the roof is definitely partially open up. Wind sensors should be installed to close the roof in stormy climate. Movable shade is generally installed with the open up roof design. It reduces heat load by reflecting the suns rays back out. The shade curtain ought to be of a porous design to allow heat to flee. In northern climates a power blanket may also be installed to lessen 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 system, 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 rain or snow. A-roof styles shed the rain and snow to an interior gutter system. Styles which will carry up to 35 lb/sq ft snow load and 100 mph wind loads can be found. The roof opens in sections by moving the industry leading of the curtain. One gear motor will deal with up to 50,000 sq ft of roof Heating system is more difficult than in a conventional greenhouse because of the single layer plastic and better infiltration through gaps and cracks in the seals.
