I've been looking for the monthly CO2 level charts & had 'em right on my desktop !!!
https://www.co2.earth/daily-co2
https://www.co2.earth/monthly-co2
I don't understand the difference between NOAA & Mauna Loa, other than the obvious - NOAA is about 9 ppm lower.
The original suggestion came from Ed Rosenthal. I was reading one of his pot growing books at Cody's on Telegraph in Berkeley (in the pre-Amazon days. Boycott Amazon !!!)
Anyway, he advocated 389 PPM. And he was right, the extra CO2 made for some magic Cannabis.
>>> The Question
Does something EXTRA start happening when CO2 levels get up to a certain point ? (besides wildfires and one's crop being burned down)
If you go from 411 to 415 ppm, do the plants get extra excited ?
Is it more of a linear thing - more CO2 = more plant weight ?
Just wondering if anybody who had a CO2 meter & went to the trouble of measuring plant weight, to assess growth rates, if they found anything interesting.
I figure it's either a Linear Thing OR a diminishing returns thing.
But I can't help but wonder if there is some magic CO2 threshold where the plant just goes BANANAS.
