c02

i work part time in this resturant and they have loads of these cylinders that are used to connect up to the beer pump, is this c02 in these cylinders?

they will have a mix of Co2 and nitrogen I think

I don't think there's nitrogen in those tanks. I'm pretty sure it's straight co2.

yep, its CO2. If you check on the bottle it should state the contents. from experience brown bottles tend to be helium, green is 02, grey is CO2.

hm say it does contain some nitrogen aswell, will this hurt the plants???, also when i have the bottle to i just open it up and let it spray into the air?

The air you live in and breathe, as well as all the plants around you, is comprised of approximately 70% nitrogen. Depending on the ration of nitrogen to carbon dioxide, I highly doubt it will cause any harm.
