I would say in terms of oxygen... possibly but adequate airstones would also be. Higher temps equal faster bacterial growth both good and bad so I would say higher temps would allow for less time to react in the event the of bad bacteria.Would a possible advantage of these be being able to run much higher water temps than normally would be?

I can't find the info again but perfect plant health for roots and veg is found when there is an equilibrium between the water temp and ambient temp but ofcourse that only works up to a certain temp which I don't think would be above 74.
If I wanted to spend that amount of money I would totally try but I'm still a bit cheap.
I have not been able to find anyone growing cannabis with it, neither has GreenEnvy, who sells it, but a lot of growers are private for good reasons
I don't think equilibrium works when ambient temps are mid 80*+, as they are here 8 months a year: water should be below 68. Its just easier to maintain water temp when ambient is < 75*s, only about 4 months a year here. And running ac in that room adds $100/month x 4 months is, well...why I am willing to try the 2020
Waterfalls are a very good alternative, but must be on a deep cycle timer to minimize heat build up: pump + timer + plus fittings + tubing ~ $100 +
During hot months, I rotate blue ice packs every couple hours. That keeps me from having much fun away from home.
Now, IF using the 02Grow allows temps ~ 80*s, or, if it allows me to flood every 3-4 hours (by allowing the roots to absorb considerably more nutrient from each flood) and get the same benefit as flooding every 2 hours that, too, would be HUGE

Temperature and gasses will always try to reach equilibrium. Root and shoot temps do affect growth. Warmer temps change the viscosity of the liquid in plants and in studies I have read below 64f can slow growth. And an optimal for growth is around 75f in those same studies. Now in the case both air and water temps are equal... reached equilibrium. Since this in not usually the case in nature or our man made environments the higher shoot and leaf temps would minimize this effect since the plant feed itself through siphoning the water combined with nutrients, the root temp effect is less but not to be discounted. Basically yes higher water temps could provide for easier uptake of nutrients but this is most effected by transpiration rate and the difference between root temps of 68 to 75 would more than likely make minimal differences in growth while creating a more favourable environment for bad bacteria. Different bacteria can survive or thrive in certain conditions and in this case the bacteria we want fair much better in cooler temp than the bacteria we are trying to avoid. Can higher temps be done... absolutely but is the risk worth it... imo not so much.I can't find the info again but perfect plant health for roots and veg is found when there is an equilibrium between the water temp and ambient temp but ofcourse that only works up to a certain temp which I don't think would be above 74.

Agreed on all accounts but one of the requirements for negative bacteria to thrive is a low oxygen environment, correct or not, I'm really asking?
So if your using these 02 emmiters which would allow you to keep maximum 02 levels even in high temps then wouldn't that mean any concern for bacteria growth would not be any higher than with lower temps?
I'm not being difficult but just trying to understand better.
Most of the reading I've done have stated the growth increase from higher temps is not negligible at all. I've never done it so I can only go by what I read. My only problem with the whole concern is oxygenation by this new system "should" basically remove 'heat' risk in terms of bacteria growth.
Hmm I can't get the full study.. just the abstract. Did you look at the full study?Here you go!

Only change is water temp.
