co2 in clone room?

My clones are on day 4 and 5 in root riot plugs. Is it ok to run some yeast co2 in the room? I currently have a 1 gallon jug of it in the room, or should I put it back in the veg room?

a fermenting a gallon of sugarwater probably wont make any noticeable effect either way. But i'd say if you're determined to do it, just keep it in the veg room

Clones don't photosynthesize from what I have read. They would once they grow roots, but not after cutting.

ok thank you for the information. I put he co2 back
