Is misting plants with seltzer water a good souce of c02??

I watched this video on you tube where this guy recommends spraying plants with soda/seltzer water to provide additional c02.....anyone have any insight on this idea????

Yes carbonated water is carbonated with CO2. You can foliar feed with it.

Make sure it is sodium-free

Why sodium free????

not completely sure WHY, but too much salt will lock up roots, and they will not be able to get nutes from the soil

compared to the sugar/yeast co2....I wonder how soda water/seltzer rates

i had the idea of setting up a pump and timer in a large reservior of soda/mineral water, so that it turns on mists the plants through a system of pipes and sprayers once a day or something...

good idea?

I think the problem with that idea is....take for instance a liter bottle of soda...with the lid tightly secured, the soda still has its carbonated taste....however if you leave the lid off for even a day the soda gets flat(CO2 is gone)....with your idea, you would have to keep the container storing the soda water air tight...A pump will not be able to work sucking liquid from a sealed container...It would create a vacuum...( I think I,m right about this...not 100% sure)

Thats exactly correct, you would need the soda water air tight, but there would have to be an opening somewhere for the pump to work, otherwise theres a vacuum, if there was an opening it would go flat...

I have a different idea, one tube leading out of the soda water container near the bottom, and have that tube going straight up [so that the water in the container and in that tube both are at the same level]. Then have a tube at the top not dipped in the soda water at all, the soda water container would have to be completely sealed [the smallest hole and it really wouldn't work well, and if it did you would be losing a lot of efficiency], and them pump would work by pressurizing air from the top tube, which would push the soda water up the tube that comes out the bottom. I would think because you are constantly pressurizing the container, it shouldn't go flat, at least not as quickly. What I mean by pressurizing the air through the top tube is doing something like blowing down it, except you would need a mechanism to do it. Haha just thought I would share this modified idea.

also if you were to put the carbonated water in a sealed container with a tube going to the bottom of it ,and put a sprayer nosel you could use the waters compression to disperse and then the co2 would go to your plants through liquid and naturaly by increasing atmospheric co2 levels in your grow room

I wonder if a humidifier with carbonated water will be a good continuos source of CO2.... hmmm i wonder if that would even work like i think.

unless you are keeping your temps high in a tightly controlled environment and using meters to control the CO2, your plants will get all the CO2 they can use from a steady supply of fresh air.
