No, he's not confused:
Supplemental carbon dioxide in greenhouses | ontario.ca
The benefits of carbon dioxide supplementation on plant growth and production within the greenhouse environment have been well understood for many years.
For the majority of greenhouse crops, net photosynthesis increases as CO2 levels increase from 340–1,000 ppm (parts per million). Most crops show that for any given level of photosynthetically active radiation (PAR), increasing the CO2 level to 1,000 ppm will increase the photosynthesis by about 50% over ambient CO2 levels.
