What is the easiest way to provide sufficient CO2 to your plants?

[justanotherbozo]

thanks alot.. I was thinking if I even tried I was going to have to but the meter which the cheapest was $250... I was also thinking the room would need to be sealed. I think Ill just wait until later on to work with CO2 like that

as you have already had some great advice from search1st and headshake, all i can
do is share my experience with the vinegar drip. lol, what a pain in the ass.

i used it for about a month and discontinued it as more trouble than it was
worth, frankly, i'm a micro-grower so it's just not necessary.
