I have been meaning to look this up for a while, but it occurred to me that if you sit and talk to your plants you are breathing on them too.
I wanted to know how much CO2 would i be adding if i sat with them for 5 minutes? So, i looked it up and this is the answer i got.
An average adult breathes about 0.5 L of air per breath at rest. Normal air contains ~ 0.03 % of CO2 which gets enriched to 4 % of exhaled air. The difference, 3.97 % is what you exhaled. One mole of air at room temperature have a volume of ~22.4 L (use ideal gas equation p*V=n*R*T, p=pressure [bar], V=volume, n=amount in mole, R=ideal gas constant, T=temperature [Kelvin]). 1 mole CO2 is equivalent to 44 g.
So, 0.5 L*(1 mole /22.4 L)*(44 g / mole) = 0.982 g
One breath therefore contains ~ 1 g of exhaled CO2
Note: Some of the gases are not ideal (mostly CO2), the volume of one breath depends on the person (sex, age, fitness, size) and the activity. It can be up to 2 L at least. But it is just an approximation anyways.
Seems alot cheapaer than using pub bottles.

neighbour told me he could hear me swearing all the time in my workshop, thought it was funny
