CO2 sources? I need some

[Winks]

Ive grown a couple times already, so you can understand why I'm embarassed to be asking this question now, but what are some sources of CO2 that are simple to use? and im not talking about machines or anything, i have no room for that shit.

I have found a product that I have not got the chance to use, however I have talked with 3 seperate grow shops and all think it is a great option to a burner or messy kitchen recipies.

hope the link works, I'm good with green stuff, not this electronic part.

Anyway think of it like a CO2 Alkaseltzer. You can even use part of the tablet for smaller spaces. I'll be getting some here soon, I'm also going to get a CO2 meter for the money I'm saving. Just to be sure that I don't fog too much. It also has a "clean scent" so maybe it will help with the odor during flower.

Check it out, then see what you think.

Happy Growing
