CO2 is "only" 1% of the atmosphere,

More like 0.35% actually.

0.35% in 1988.

April 2008 MLO has 387.19 PPM, or 0.38719%
Rounding fun
0.3872%
0.387%
0.39%
0.4%

Ok, let's just say 0%

A well designed and operated hydroponic grow room would round that
down to zero fairly quickly, if it weren't for those pesky humans
there.

Human etc respiration is a bugger isn't it ?

On a global scale, no, it isn't.

I'd ask you to do the math yourself, but it would be fruitless.

I have done ages back. I suggest YOU do. You might get a surprise.

And never mind the cows.

" Cow emissions are more damaging the planet than CO2 from cars

The world’s 1.5 billion cattle are most to blame. Livestock are responsible
for 18 per cent of the greenhouse gases that cause global warming, more than
cars, planes and all other forms of transport put together. It generates 65
per cent of human-related nitrous oxide, which has 296 times the Global
Warming Potential (GWP) of CO2. Most of this comes from manure. "
