Honestly dude i think you missed my point.... Airstones, water falls , water movement ALL increase DO. The exchange occurs at the waters surface with turbulence/movement which is what all of those methods create. What I was saying is there is no one "right" way. Your delivery comes off as very self righteous as if airstones cannot work which is completely untrue. Waterfalls increase DO, water movement increases DO , airstones increase DO..... Do what works for you....Many ways to skin a cat . So before you get all philosophical comparing your plight to einsteins ...
pic or didnt happen
Some things I can add to this thread . .
1 - Different types of roots grow for different conditions. I have left cuttings in a spagetti sauce jar for 2 months and only refill with tap water . . the roots grow for no-bubbles\low oxygen and thats what they are use to. They NEVER need bubbles.
2 - If the plants grow roots in bubbles then you cut it, your changing what the roots are use to so of course they kook out.
We were running around 2HP of air in a UC16XXL drawing outside desert air (sometimes 100 degrees before going through a piston compressor and getting even hotter)_ . . and it fucked the plants up . . they grew like 6 inches in 3 weeks with CO2 and DIMLUX and AC . . then we noticed 2 plants were doing OK .. it was the 2 with cloggged stones and no bubbles in the pod. They didnt get over fed from nutes and they didnt have a hair dryer up their ass blowing 120 degree compressed air all day . . we killed the air to the pods and all the plants got happy in 24 hours.
There is another factor that happens with hyper aeration - the constant changing of state of the root membrane from dry to wet that allows molecules to pass much more freely, hence the reduced PPM with higher aeration
This bonus multiplier increases the yield while increasing the risk of over feeding and reliance on (extra) mechanical systems.
Therefore the safer way for us for now is to go no pod air and raise the nutes to the Heath target of 1.2 EC
Thx FooDoo for this thread and your application of logic!
always thought oxygen was the Achilles heel in DWC.I cant understand how you guys are running these plants in water thats just sitting still and not experiencing major issues.

I've used Venturi's in my system and since switched to a waterfall. Venturi's drastically reduce circulation without high pressure pumps. Both work good but IMO the waterfall is much more effective for the same size pump.
Mosquito control? Breeding in your res?I would too, but mosquito control is my main issue
