Because newbies often ask this question about CO2 concoctions, along with seltzer and tonic water sprays. As you seem to ask the questions of a newbie, you got the standard newbie answer.

And while we are on the subject...Myself and a few others in here that troubleshoot, offer advice, and yes...answer newbie questions...play to a larger audience than just the person posing the question(s). There are shitloads of lurkers reading this, that may need the additional info I've provided, regardless of whether or not you feel it is relevant.

So you feel you need the CO2 shortcut, and want to know how to go about making it today...? What CO2 level are you at now, and what levels do you wish to achieve with the soda-bottle CO2 machine? Where are you going to place it...above or below the plants? Are you going to use it at night, or during the day? Is this ok for cooler temps, or warmer climates...? Closed room, or open ventilation? Increase nutes, or cut 'em back? Any personal dangers in using CO2?

CO2 isn't a shortcut, it's a tool. Likely best to know at least why you are using it.
