The concept of cooling a greenhouse with thermal buoyancy and wind goes back to the beginning of controlled environment. All greenhouses constructed prior to the 1950’s acquired some form of vents or louvers which were opened to allow the excess heat to flee and cooler outside air flow to enter.
When polyethylene was developed with large sheets within the whole roof, placing vents on the roof proved difficult. Engineers then came up with the concept of using followers that draw outside air through louvers in one endwall and exhaust it out the contrary end. With thermostatic control, this was, and still may be the accepted method for cooling many structures where positive air flow movement is needed.
Growers with hoophouses have discovered that roll-up sides work well for warm period ventilation. Both manual and motorized systems are available. A location with good summertime breezes and plenty of space between homes is needed. It can help to have greenhouses made with a vertical sidewall up to the elevation of the attachment rail to reduce the quantity of rain that can drip in.
