only co2 water

I know for a fact that using no soil with plants works fine as long as the roots get plenty of oxygen but i had to ask myself the other day...

why would the roots need o2 instead of co2 like the rest of the plant?

wont co2 work just fine as long as not only h2o?

while thinking that i realized that carbonated water is h2o with co2...

this seems like a godsend!!!
wouldnt co2 water alone be the best thing in the world to grow with? no soil, just straight co2 water?

has anyone tried this and if so please post results with statistics if possible.

(i know that co2 water helps plants, i want to know if plants will grow using ONLY co2 water.)

thanks in advance for any help guys, yall rock

The roots do not use co2 at all, they use oxygen only. The greenage uses co2, but most applications are not effective to really do any good.

When you don't use soil, it's called hydroponic gardening. The idea of hydro is to maintain better control of the nutrients plants use during growth. Most hydro systems flood roots a few times a day with the nutrient water for a short amount of time. This causes the plant to experience drought/flood/drought/flood stress which will maximize nutrient use in turn maximizing growth.
In order to do this, a grower using hyrdo has a reservoir where the nutrient rich water sits waiting to be pumped into the container where the plants rest, flooding the roots. The reservoir only gets changed every week or two(depending on what stage of the grow your on).
If you have been drinking soda your whole life like me, you'll know that carbonated water left out for more than a day goes completely flat(all CO2 has escaped). So in order to test this in a hydro set up, you would need to change your reservoir everyday. This means you start over with nutrients, ph, temp, etc. Nutrients are not cheep, so this experiment would be very costly and time consuming.
Also, regarding the website you posted:
A)The plants are not marijuana plants. The plants are dumbcane or the "mother-in-law"plants. A common house plant that does not seed. No plant is the same, and no plant responds to the same situation the same.
B)Those plants were grown in soil, so most of that CO2 transpires up and out of the soil before the water is absorbed in the roots.(depending on pot size and root mass, it could take a plant up to five days or even more to use all the water from one watering). The CO2 transpires up to the foliage, which simulates regular CO2 enrichment.

this is true if you are feeding multiple plants.

What if it was one or two plants being watered a certain amount daily with new water. There would only be enough given to the plant daily to feed it so there would be little to no nutrient loss.

About 6-8 oz at a time in intervals with added nutrients. This would allow saving money with nutrients, keeping the plant nourished the correct amount at all times, and hopefully giving it a shit ton of co2 with the carbonated water.

what do you think?

I think it could work, maybe with good results. I don't know if anyone has tried this. if you do try it, make sure to set up at least one plant in reg water as a control for the experiment.
Also, you still use a reservoir in small set ups because plants take time to consume the nutrients from water. If you throw out the water everyday, your throwing out a ton of nutrients with the water that has barely been touched by the plants. Also, some nutrients and trace minerals take longer to break down and be consumed by the plant, so you may have problems adjusting a proper nutrient balance as hydro nutrient cycles are formulated to accommodated this.
