The concept of cooling a greenhouse with thermal buoyancy and wind goes back to the beginning of managed environment. All greenhouses constructed just before the 1950’s got some kind of vents or louvers that were opened to enable the excess heat to flee and cooler outside surroundings to enter.

When polyethylene originated with large sheets covering the whole roof, putting vents on the roof proved difficult. Engineers then came up with the concept of using followers that attract outside air through louvers in one endwall and exhaust it out the opposite end. With thermostatic control, this is, and still is the accepted method for cooling many structures where positive atmosphere movement is needed.

Growers with hoophouses have found that roll-up sides work very well for warm season ventilation. Both manual and motorized systems can be found. A location with good summer time breezes and lots 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 lessen the amount of rain that may drip in.
