yes it would,during the lighting period the plant will use oxygen from the root system to metabolize and absorb nutrients while the foilage uses light and cO2 turns them into sugars and growth hormones,the plant will respirate all the oxygen it recieves in the lighting period,during the dark period the plant releases the cO2 gathered up during day and uses it ,i've read books that advocated the use of cO2 during the dark period,but now these outdated thoughts and theories are revised since the plant biology has been futher examined ,we now know that cO2 is beneficial especially during the light period....bonbon Oxygenating water
