Article Could Houseplants Improve Indoor air Quality in Schools?

Hi Elena,

If you are trying to lower CO2 levels with just a few house plants (or even a lot of them!) to any significant degree then it is not so much the plant selection that is important (well plant selection is important but hear me out) as compared to the environmental conditions in the living space.  Typically, light levels in a home are quite low, even if we as humans perceive the light to be bright, which is why shade tolerant plants are often marketed as houseplants.  The light levels in a home are often close to the compensation point (basically the point at which there is enough light for photosynthesis to balance respiration).  The result is that plants will often be releasing almost as much CO2 (respiration) as they are taking up/capturing (photosynthesis)(if they are in fact growing then photosynthesis must be at least a little greater than respiration).  In addition, the microbial community in the soil or growth substrate are also respiring and releasing CO2; so in fact, the net 'system' (plant and microbial community) could actually be a net source rather than a net sink for CO2 under some conditions.  Having said all this, if there is an option to add additional light to the system then you can push the plant further up the light curve and capture more CO2.

There are many other aspects to the relationship between plants and indoor air quality; my response is solely related to CO2.

Best regards,

Thomas
