The concept of cooling a greenhouse with thermal buoyancy and wind dates back to the start of controlled environment. All greenhouses constructed prior to the 1950’s got some form of vents or louvers which were opened to allow the excess heat to flee and cooler outside atmosphere to enter.

When polyethylene was developed with large sheets within the whole roof, putting vents on the top proved difficult. Engineers then came up with the concept of using fans 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 atmosphere movement is needed.

Growers with hoophouses have discovered that roll-up sides work very well for warm time of year ventilation. Both manual and motorized systems are available. A location with good summer breezes and plenty of space between homes is needed. It helps to have greenhouses designed with a vertical sidewall up to the height of the attachment rail to lessen the quantity of rain that can drip in.
