Here is a blurb:
Aeroponic system
My observation is that plants grown in aeroponic and hydroponic systems benefit most from dissolved oxygen. The photos below are from Choice Growers in Strathmore, Alberta, which uses an aeroponic system. The roots are directly misted with oxygenated water.
The plants shown in Picture 3 have roots with oxygen levels of around 8 to 10 ppm. Note the roots are pure white, contains lots of feeder roots and an abundance of root hair. This translates into very good top growth (Picture 4 ).

I just grabbed that from the top of a google search. This is the "simple" answer. The plants need it for maximum root potential and therefore plant health and vigor.
So it's not as simple as the roots drying and absorbing the oxygen out of the air. They need to absorb it through the water when its dissolved. Makes sense, this is kind of why sometimes my over watering remedy in soil is to actually water with fresh water that has oxygen in it, just enough to get the plant through on the way back to a healthy moisture level. It does work.Here is a blurb:

Actually I think plants can absorb directly from the air, just like leaves do with CO2 during photosynthesis.So it's not as simple as the roots drying and absorbing the oxygen out of the air.

Now what if you could safely inject elevated o2 levels that you want into the rootzone and control them. Without tanks, refills or the risk of explosion In all types of grow systems cost effectively with equipment that lasts yrs….So it's not as simple as the roots drying and absorbing the oxygen out of the air.

Got it.Actually I think plants can absorb directly from the air, just like leaves do with CO2 during photosynthesis.
I remember reading something about cannabis will use oxygen at night.Got it.
Yes, the root zone is approaching 90. It never quite gets there but close.Is the root zone 90?
Phase change the oxygen at the post supply/pre nozzle level?
Supply (pressurized) > drop pressure> nozzle
Too complex...
Cool it like an engine. Aluminum slab with internal channels, wrapping the nozzle bank and have a glycol radiator with peltier attached to drop the temp.
I would bet the 02 levels raise functional temp enough where 5-10 degrees could be skimmed at nozzle. But, it's got to go somewhere.
Yeah this is a brain buster. Your running up against the 2nd law here.
Increase the res volume?
Yeah this @Moe.Red guy dont fuck around…. I believe the term im looking for is proper.Wow you guys are really getting it dialed. Impressive.
Yeah, I figured you had it goin on. I was right to feel inspired by you. Damn. Great looking, CLEAN room(s).Since we have a few new folks (the more the merrier) I'll show you what we are working with on this project.

What role does the oxygen play in to the root zone? Is it just keeping aerobics alive or feeding the plant? or both? Honest question, I've seen aeroponics done never done it myself.

Wouldn't that just be the erroneous interpretation of the definition aeroponics? We know full and well it's not growing in just air. It's hydroponics through and through and I can only imagine you're benefiting from the dissolved oxygen levels of both the water and the atmosphere.aero and aeroponic leads to the erroneous conclusion that the system would bring a better oxygen supply
I'm a little confused here, if plants are dependent on dissolved oxygen in water, how can they be no better supplied with oxygen than in an air-filled substrate? Wouldn't the air/vapor mixture be an air-filled substrate? And if that air carries an adequate or optimal amount of water with an adequate or optimal amount of dissolved oxygen, wouldn't you see those oxygen uptake mechanisms benefit from the hybrid environment?if the roots are always covered with water, even if it is only a thin film, they are dependent on the oxygen dissolved in the water and can not be better supplied than in an air-filled substrate in which the roots have contact with atmospheric oxygen

I would think there would never be a constant film of water given that the air/vapor mixture is constantly recycling physically and physiologically. And I imagine that exchange is where you see a similar benefit of a very-porous media/substrate, perhaps greater. This statement, to me, seems particularly in favor aero/fogponics performance.
I think the information provided is good for standard grows.In summary:
More oxygen to the roots does not mean more growth. There must be enough oxygen so that light and nutrients are optimally utilized.
Here you can also refer to Bugbee: Light is the engine that drives everything, and all other factors must match it.
Coco perlit is probably ideally suited to provide an optimal root environment for the plant under all conditions.
Very good water holding capacity, very good oxygen supply and other advantages, which I have already posted above in relation to beneficial additives and natural growth promoting benefits of coco coir.
In my opinion, the aero and aeroponic leads to the erroneous conclusion that the system would bring a better oxygen supply.
From a scientific point of view, however, I see it after the article that an aeroponic system in terms of oxygen supply is comparable to a DWC, in which the water is also always well aerated.
As I said, if the roots are always covered with water, even if it is only a thin film, they are dependent on the oxygen dissolved in the water and can not be better supplied than in an air-filled substrate in which the roots have contact with atmospheric oxygen.
