Comment on how do plants in a green house get enough co2?
untorquer@lemmy.world 10 hours agoIt’s called diffusion. Unless the greenhouse is hermetically sealed, and the rate of consumption does not exceed the rate of diffusion, the ratio of CO2 will be similar to that outside.
A simple vent will be enough if not just small gaps in the structure.

Also, most green houses have fans that can help circulate air in from the exterior.

I’m inclined to think the fans are more for fanning the plants so they can perspire and breathe more readily. Many plants need a breeze to grow well.
