CO2 bottled water possiblities...

Hey guys, I heard a grow tip on CO2 in ordinary sparkling water/ bubbly water bottles at the store. From what I understand is, you put this stuff in a spray bottle and spray your plant with it....!! I know there must be more to this than just... that! How would this work with 2 plants at the 4th week of flowering??? Do you daily spray the entire plant or just the underside of the leaves and what about the buds..............?:rasta:

I saw a how to grow video where the dude was spraying with co2 water every time he came in the room..

curious on you other guys' thoughts..

Make sure you get the one with NO SODIUM.. it might be called.. "lite"

The only way i could imagine that this is effective is if you have very poor circulation in the room. Otherwise, there just wouldn't be enough for long enough for it to have any effect at all.
