In an attempt to reduce the greenhouse effect found when experiments are carried out in greenhouses, a new type of plant growth chamber was designed. Cylindrical chambers, 240 cm in height and 300 cm in diameter were constructed from Filon, a translucent corrugated acrylic fiberglass plastic sheet. A squirrel cage blower provided air at a rate of about 2.5 changes per minute. Activated charcoal filters were installed in the incoming air stream to remove photochemical oxidants to produce clean air. A 45/sup 0/ baffle was installed to displace the trailing edge mixing layer above the top of the chamber and thus sweep it clear by utilizing the vertical momentum component of the wind which is created locally.
