The idea of cooling a greenhouse with thermal buoyancy and wind dates back to the beginning of controlled environment. All greenhouses built prior to the 1950’s experienced some form of vents or louvers that were opened to allow the excess heat to flee and cooler outside air to enter.

When polyethylene was developed with large sheets within the whole roof, putting vents on the roof proved difficult. Engineers after that came up with the concept of using enthusiasts that draw outside atmosphere through louvers in one endwall and exhaust it out the contrary end. With thermostatic control, this is, and still may be the accepted method for cooling many structures where positive atmosphere movement is needed.

Growers with hoophouses possess found that roll-up sides work well for warm season ventilation. Both manual and motorized systems are available. A location with good summertime breezes and lots of space between homes is needed. It helps to have greenhouses made with a vertical sidewall up to the elevation of the attachment rail to reduce the amount of rain that can drip in.
