Minimum and maximum (or rather, optimal) level of CO2 for plant growth
MINIMUM
Don’t let anyone tell you that CO2 is a pollutant! This picture is from peer reviewed article: https://nph.onlinelibrary.wiley.com/doi/pdf/10.1111/j.1469-8137.2010.03441.x
Check it out for yourself. This picture is worth a 1000 words.
OPTIMAL LEVEL
1500 ppm is the OPTIMAL CO2 level for commercial greenhouses. That’s what we ought to aim for, unless it is proven that that level can cause other harm.
” 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]
FURTHER:
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.

Dear Sanjeev Sabhlok: March 5, 2021
Thank you for your article.
I am planning to construct various styles of greenhouses in the near future.
Your information on CO2 levels was what i wanted to know for design and operational
needs.
I hope for you the best in your future.
Note– there is a tremendous need for this information to be disseminated on a wider
scale — due to the monstrous misinformation and agenda of those seeking to limit
instead of increase to optimum the amount of CO2 in the atmosphere for nefarious
political agendas.
Again, Thank You.
sincerely,
K.D.
