@PikesCore24 Science says that plants grow optimally well over 1000ppm CO2. I wonder why they would evolve for such a high CO2 environment? Also, I live in Phx AZ where the temps are over 110F every year going back in recorded record as far as you can and plants grow great here given water. Grow vegetables in the winter and grains in the summer.

@davidstockhoff8801 "AI Overview Learn more … The optimal level of carbon dioxide (CO2) for plants depends on a number of factors, including the type of plant, the stage of growth, and the environmental conditions: General guidelines: The optimal CO2 level for most crops is around 1,000–1,300 parts per million (ppm). Seedlings: For seedlings like tomatoes, cucumbers, and peppers, a lower level of 800–1,000 ppm is recommended. "
