Carbon dioxide dosing in commercial greenhouses – gas ...

· In greenhouses, the growth rate and development of all plants can be improved by controlling CO2 concentrations at levels of around 800 ppm. This is approximately twice as much as the natural concentration of CO2 in natural ambient air. Higher CO2 concentrations up to 2000 ppm have been used in greenhouses and hydroponics, but each incremental increase in CO2 levels above 700 …
