Question about co2

A question from a fellow grower:

if the normal air co2 level is about 350 ppm…and i boost that number with my exhale…can i reach example 1000ppm without co2bottle just with my exhale?

LOL…I doubt it. Happy Growing :slight_smile:

You might pass out from hyperventilating trying to get that much co2.
