Grow plants in aqueous carbonic acid.

I think it would be cool to grow plants in an aqueous carbonic acid. First of all don't say carbonic acid hasn't been synthesized, it can be made in pure form by adding equal molar mass amounts of water and dry ice to a supercritical liquid chamber and can be formed in an aqueous solution by bubbling cold CO2 through carbonated water at just above freezing point. Anyway I was thinking that I could have soil with strawberry seeds in it submerged in 50/50 ratios of carbonic acid and water being exposed to UV light.

A majority of plants, including cannabis, grow best at near neutral pH . . .
Acidic conditions will likely 'lock' up some plant nutrients, resulting in poor growth!

So a ph of 5 or 6 isn't good?

I think you have that backwards, most plants DO like a slightly acidic growing environment. The nutrient lock you speak of happens when the pH rises, since most of the trace nutrients which are metal cations precipitate out of solution as insoluble hydroxides and what not. That is why iron chelate is recommended for iron deficient plants as it soluble in much more alkaline conditions and thus readily absorbed.

Also plants like dirt that's why the grow in dirt and dirt like materials. Algae and kelp like water you could try those. My guess is roots would die from suffocation pretty quickly or from to low of a pH.

That's what I said?

On wikipedia is says that even a single molecule of water causes the carbonic acid to revert to CO2 & H2O.. In the absence of water it has a half life of 15,000 years..

So how would this be different than just carbonating your water right before watering the plants?

Besides, plant root need oxygen, not CO2.
