CO2 provided by person breathing in same room as grow tent?

Basically, does a person spending most the day in same room as a grow tent provide enough CO2 from exhalation to make supplementary CO2 unnecessary?

I know supplementary CO2 for home growers is a contentious issues as is. :sweat_smile:

CO2 supplementation is pretty much always unnecessarily unless you maintain the environment necessary for a plant to utilize the excess CO2.

That’s been my impression so far too. Just wanted to get some other perspectives too. Thanks @MidwestGuy
