Co2 in air is about 0,03 % when there is good vegetative growth this could fall down to a 0.01 this is not suffiient enogh for the plant, also I had a biological eperiment which shown that temperature 36 is the best, however my planting are is about 25 (hope not for long) I'm a new to growing but have a bakground knowledge which I will try to use and play around with it. Hope I will have good results using your advises as well.
