I have not been able to find any info on here about co2 for autos. I know how to do it with photos, but would like to know if there are any clear differences. Things such as say should you aim for 1500 ppm with autos too? Does it affect their potency in a negative way? Does it benefit them any more or less than photos? Any info is welcome. Thinking I should be ready to do it just after the new year.
