The Canadian Ministry of Agriculture recommends supplementation of 1000 ppm to reach 1400 ppm during the day. More has little effect on growth, more than 1800 ppm has a negative effect. I stop at 800 ppm because I don't get it for free. Workplace safety regulations limit is 5000 ppm. To put it into perspective: 100 ppm means 1 CO2 molecule out of 10,000 air molecules. This is the difference in global CO2 concentration between 1900 and 2015.

Fortunately no one will ever substantially reduce CO2 output as long as it is related to GDP and feeding the rising global population. CO2 is the 'Gas of Life' and naturally, plants love it.
