A human exhales about 2.3kg CO2 per day. So that's 12/(12+216)2.3kg or 630g of carbon. A plant maybe absorbs 1g a day? Lets say a bit more... You probably need somewhere in the range of 500 indoor plants.

- detaro 4y agoa number I found quickly says a greenhouse full of crops consumes 0.12-0.24 kg CO2 per hour per 100m²
- cinntaile 4y agoI don't think those numbers are applicable to house plants. Crops grown in a greenhouse are specifically grown to increase their mass in as short a time period as possible. Regular house plants usually don't increase their mass that much (you don't really want them to), they don't get nearly as much energy and nutrient input as greenhouse crops.
- detaro 4y agoI thought "you'd need a large apartment worth of plants per person" was bad enough already, without caveating it on plant type
