Club Soda or Tonic Water?

I know this general question has been covered before, but I don't think there is a clear answer.

I have heard that when using carbonated water to mist plants, one should not use club soda because it has sodium that can clog the stomata. My first question is how would the sodium clog the stomata? From what I remember about biology, don't plants have sodium channels and such to handle that kind of stuff? I could see the salt forming a solid when the water dries and clogging the stomata, but then again, both tonic water and club soda have tons of potassium salts, so I don't get why people say one is better than the other. I went with the club soda, because I found a sodium-free brand and it had the least amount of other salts compared to tonic water and other brands.

Can someone explain why one is better than the other in more detail? I'm a science lover, so I like to know how things like this work lol. Plus I don't want to mess up my plants.

Thanks!

you have actually gotten more scientific with that post than i have seen in a lot of the seltzer threads. i am not a scientist, not even close, more of a freelance information acquirer. i had heard about the clogging, but had not heard it explained, so i just assumed it was because the salt dries and clogs the stomata. i did not know the ditty about both having potassium salts. i'm also not sure if it has something to do with ph. i'm thinking that any adjustment of the ph would render the liquid devoid of co2 what with the stirring and all. i guess i'm no help but i would be more than happy to bump it up to see if someone else knows.

I just wish I could remember more from my biology classes. They weren't that long ago, but my memory isn't the best

On a side note, relating to my plants, it seems that growth has slowed waaay down. They are 9 days from seed and just over an inch tall. It seems a day or two ago that the rate of growth was just cut in half. Is that normal? It's my first grow, so I'm not too sure. Also, how deep should the soil feel dry before I water when they are this young? I read that watering a few times a week or as little as once a week is normal, but it seems like my soil gets dry really fast.

Okay sorry for hijacking my own thread, after this back to the carbonated water question

i mix seltzer water wit my dutch master liquid light plants like it but is just air n water others have extra baggage
