I have been in this game for a long time and common wisdom has always been to keep your CO2 levels at 1500 ppm for best results. Recently when doing some research I ran across a thread that says not to go over 1200 ppm and that 1100 was ideal. I have been away from the grow forums for a year or so and a lot has changed in that time so I was wondering what do you guys think about the ppm debate? The linked article below is the one I am referring to and it is one of the few I have seen that actually cites peer reviewed studies. What say you farmers?
