Apologies Rizlaninja for the off-topic stuff. I've never done what you are doing with the drip system, so I can't directly advise you there. But as long as oxygen can get to the roots, and the dripped water isn't stagnating around the taproot, seems like it should be fine.

I got a couple shiny pennies.
I agree with Chromophore.
Without a parallel, "no extra CO2 grow" as a yardstick , all you have is an impression of benefit.
A little research tells me that CO2 becomes detrimental when >1500ppm. so, careful with the dry ice.
I also read that there is little benefit at ordinary temperatures, but definite gains at >80 degrees F.
That makes sense.
At normal temperatures all influences on the growth are well balanced.
Increasing any one influence is wasted
However, if one of them goes out of balance (High Temperature), one or more others can be augmented to restore balance.
With living things, it's all about balance.
In the heat of the summer, I port air from the veg room, to the flower room.
Why?
Because vegging plants actually raise the ambient CO2 during their dark time and flowering plants use it day and night.
For a few hot months, I ported the excess CO2 from my wine making room to the veg. room, which then went to the budding babes as well.
Did it do any good?
Hard to say.
I only have one veg room.
Bottom line?
At less than 1500 ppm. at least it won't/didn't hurt.
And at elevated temperatures there is definite benefit.
Aloha,
Weezard

Good news is, I've done the watering both ways, and then some.
To address your question.
Yes!
IF, (and that's a big if), the water is well aerated.
I was successful with a constant drip using hydrotron.
Tends to absorb air on the fly.
Do not try it with rockwool!
And there is no problem with the tap root entering the water.
Again, if the water is air saturated.
I do that all the time with DWC.
Full immersion is no problem.

Shallow Hal I never questioned your knowledge or abilities, I was simply giving my advice on CO2 based on 28 years as a plant scientist and greenhouse technician. I offer it freely and no skin off my back if people ignore it. Now can we please stop hijacking this thread and get back to the original question?

Sounds exactly right.
You have more than enough air.
My rockwool drip experiment ended with stem rot.
Admittedly It was a very limited experiment and may have been coincidental.
Use your nose.
Sniff the cube every time you pass by.
You'll know if it starts to go sour.
