Abstract
Carbon dioxide concentration in the air is another important factor for plant growth. Its concentration in the open air varies daily. On a sunny day the CO2 level is fairly constant around 300 to 350µl/l due to photosynthesis by plants, and it rises to around 400 to 450 at night. CO2 level is more important under cover, especially in plastic houses where air exchange is normally restricted in order to raise temperatures in a cold climate, and as a result then carbon dioxide concentration falls below the outside level during the daytime. Sometimes, therefore, CO2 enrichment is conducted in plastic houses.
