Plants do not take in O2 at night and they do not produce CO2 (in any significant quantities).hi everyone i have sort of the same concept of inserting o2, i have a machine that produces 97% pure o2. and a friend tells me that plants take in o2 at night and produce co2(true?)! now if i ran a thin cord through and in between my pots having the o2 circulate in the room(small room), would this create better yields? it seems biologically correct to me but i ant no bloody biologist.... any input???????????????
