poor mans Co2??
I was drinking from a "refreshing" bottle of Pepsi max when I had an idea.
Has anyone just shook up a bottle and opened it in their grow room?
No wait that would be a bad idea..i meant aggravate it enough so that it lets the Co2 out.
I mean they are "carbonated drinks."
You could just leave the lid off and it should release the Co2 slowly.
I guess as long as you're willing to drink flat cola then it's worth a go..
Bet someones said it before.
