Cannabis mines the air for CO2 (carbon dioxide) as it uses it, so the plants are very sensitive to the CO2 level during the lighted period. Using light to energize the process, the chloroplasts in the leaf cells combine CO2 and water (H2O) to make sugar and water. This is used to fuel the cells’ metabolism and as raw material for tissue building.
During the dark period, the plant does not photosynthesize, so it requires no CO2.
