Comment on how do plants in a green house get enough co2?

Mostly it’s fine as others have stated, but sometimes they pump CO2 in there. One example is Friðheimar tomato farm in Iceland, which enhances photosynthesis by using carbon dioxide produced from natural geothermal steam](fridheimar.is/sustainability/).

I’m so mad that there isn’t a link to more info about that, because I’m wracking my brains and I can’t think of any mechanism that makes sense.

Not sure how they capture the carbon dioxide, but it’s delivered to the greenhouse itself from a giant tank outside the building. I realize that’s probably not the part of the process you were interested in, but it’s all I’ve got.
