Minimum and maximum (or rather, optimal) level of CO2 for plant growth
” You can also use a CO2 test kit to dial in your system so that 1500ppm level is maintained. As your plants grow and the garden changes, retesting your CO2 levels monthly can help you tweak your system to maintain optimum levels.” [Source]
Most of today’s complex vascular plants evolved in the last 250 million years ago when the average CO2 level was around 1200 ppm.
Our plants are therefore DESIGNED for 1200-1500 ppm of CO2. pic.twitter.com/HkQ8r0od8k

These two pictures PROVE WITHOUT ANY AMBIGUITY OR DOUBT that (1) plants were designed to thrive at 1200-1500 ppm, and that (2) the Earth DID NOT BURN UP at 1500 ppm or more of CO2.
The “CO2 scare” is the biggest pile of bogus nonsense.
