The idea of cooling a greenhouse with thermal buoyancy and wind dates back to the start of controlled environment. All greenhouses constructed just before the 1950’s experienced some type of vents or louvers which were opened to allow the excess heat to flee and cooler outside air to enter.
When polyethylene originated with large sheets covering the whole roof, placing vents on the top proved difficult. Engineers after that came up with the concept of using enthusiasts that draw outside air through louvers in a single endwall and exhaust it out the contrary end. With thermostatic control, this is, and still is the accepted way for cooling many structures where positive air flow movement is needed.
Growers with hoophouses possess found that roll-up sides work very well for warm season ventilation. Both manual and motorized systems can be found. A spot with good summer time breezes and lots of space between houses is needed. It can help to have greenhouses made with a vertical sidewall up to the elevation of the attachment rail to lessen the quantity of rain that may drip in.
