=== Supplimenting additional CO₂ ===

In a city typical Co₂ levels are around 400-450ppm. This is acceptable for a growing plant but raising levels above 1000ppm can increase growth rates by up to 30%<ref>B. A.

For more on the limitation of low Co₂ at high levels of light intensity see: [[Light#Upper limit of light intensity|Upper limit of light intensity.]]
