Carbon dioxide enrichment of greenhouse vegetable through the use of diesel exhaust gas. [Cucumis sativus; Lactuca sp]
Two cucumber and eight lettuce varieties were grown in two air-supported, closed-environment plastic greenhouses, one with approximately ambient CO2 levels, and the other enriched with 1400 ppm CO2. Diesel exhaust gas was the source of the carbon dioxide. Once the exhaust gases were scrubbed through seawater and put through an activated charcoal filter, essentially no other gases entered the greenhouse along with the CO2. Cucumbers grown in the enriched environment came into production one week earlier, and one variety produced significantly higher yields, than those grown at near ambient levels of CO2. Lettuce grown in the CO2 enriched greenhouse weighed, at market maturity, nearly twice as much as lettuce grown at ambient levels.
