I don't think it would have anything to do with getting Oxygen to the root zone. When you water or feed plants depending on soil or soiless it's the oxygen in the water itself and the water moving through the growing medium from top and draining out the bottom that pulls oxygen into the root zone. You don't typically need high levels of oxygen in your tent as the plant takes in Carbon Dioxide and releases oxygen. The fan is to bring new levels of CO2 into the tent it's not for Oxygen. Once the CO2 in the tent is used up the plant limits out on growth, that's why on a sealed room they shoot for 1100-1500 ppm of CO2 and they add CO2 throughout the day not Oxygen. If you look up the Kratky method of Hydroponics the roots are both in a nutrient solution and hanging above and as the plant drinks the nutrient solution it creates more room for oxygen to the roots. So while you want Oxygen in the roots system you want a higher than standard 300-500ppm of CO2. Nobody pumps their grow room full of Oxygen as the plant takes in the CO2 and releases Oxygen
Agreed with what you say is correct. I use a method whereas I'm using microbes in my root zone. Specifically lactobacillus, Bifidobacterium and Streptomyces species.
Streptomyces nigrescens produces
5-alkyl-1,2,3,4-tetrahydroquinolines and the
antibiotics phoslactomycin A - F. The metabolism produces natural C02 metabolism and requires
Oxygen + Sugar producing CO2
I'm not so big on growth rates these days (got that covered well) but more about overall quality; and complexity of flowers; and exceptional symbiote health accompanied by stable biological traits;
over time. Generation to generation.
The growth rates of these organisms are anywhere form 120 min to about 4 hours. An
endophyte is an endosymbiont, often a bacterium or fungus, that lives within a plant for at least part of its life cycle without causing apparent disease; The bacteria I work with eat fungi for breakfast...
lyse them.... then recycle that potential dead fungi into the system. (feeds it too the plant).
Phoslactomycins (PLMs) are inhibitors of protein serine/threonine phosphatase 2A showing diverse and important antifungal, antibacterial and antitumor activity. PLMs are polyketide natural products and produced by several Streptomyces species. I "brew" these organism on multiple, multiple levels. In the roots, and the fauna, throughout the plant fauna biome. (systemically). I firmly believe it greatly enhances overall plant vigor and health.
With growing interest in the role of endophyte to the host plant ecology, health, and productivity, this chapter discusses seed-inhabiting endophytes. These endophytes were less recognized when compared with those found in the other parts of the plant. However, they...

There has been many recent studies on the use of microbial antagonists to control diseases incited by soilborne and airborne plant pathogenic bacteria and fungi, in an attempt to replace existing methods of chemical control and avoid extensive use of fungicides, which often lead to resistance in plant pathogens.
Ie. the worse thing imaginable to happen to your prized growing or breeding lines. In agriculture, plant growth-promoting and biocontrol microorganisms have emerged as safe alternatives to chemical pesticides.
Streptomyces and their metabolites may have great potential as excellent agents for controlling various fungal and bacterial phytopathogens. Streptomycetes belong to the rhizosoil microbial communities and are efficient colonizers of plant tissues, from roots to the aerial parts.

GC content is found to be variable with different organisms, the process of which is envisaged to be contributed to by variation in
selection, mutational bias, and biased recombination-associated
DNA repair.

Streptomyces species belong to the phylum Actinobacteria and can only grow with oxygen as a terminal electron acceptor. The complex developmental cycle of streptomycetes manifests itself in the production of spores, which germinate in the presence of oxygen into a substrate mycelium that greatly facilitates acquisition of nutrients necessary to support their saprophytic lifestyle in soils. Due to the highly variable oxygen levels in soils, streptomycetes have developed means of surviving under hypoxia but they fail to grow under these conditions.
Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
ie. huge amounts of CO2 is generated by my process (I have to monitor with meter) and is a controlled fermentation method that produce many highly beneficial secondary metabolite; complex oil producing amino acids, enhance smells and terpene production; and turn fuel (various sugar)>> into C02. ie. I'm creating little RNA ->>> DNA fuel factories that the plant is able to utilize.
To be sure, this method is not for everyone, because multiple environmental factors; temps; timing and measure needs to be finely calculated. (I use spoons) But it works well for me. Oxygen is always useful at the bases of any organic grow, and any grow that has even basic microbes features. Plus; it's increasing movement of C02 where it's needed the very most, pushing it up too the leaves.
CO2 exits the soil area >>>enters the undersides of the leaves, not the tops, then the oxygen is pumped back into the soil again,
thus completing the process of plant respiration.
Here's the abbreviated version for simplicity; ie. air + moment + tiny sugar + (6) water + (6) oxygen + energy (light)>>>> === (6)CO2 I believe; Sugar, Energy and oxygen are among the (usual) limiting factors.
