This technically is all true....but monitoring your VPD is most crucial. I just listen to my plants. They'll tell you what they want or do not want AFA nutes. ( Organic is much easier in this aspect IMO) And once CO2 levels are increased and your feed program & VPD is in check, you can then adjust your light intensity accordingly and watch how the plants & environmental conditions react. Personally, when I choose to use C02, I only use it in the flowering stage.My question is, if you raise co2, wouldnt it only be beneficial if you can manage light and nutes in the proper proportions. Im sure theres a gradient on the actual ppm increase and the amount of light and nutes needed tho.
