You could do UV filtration and recycle you're water.

Yes, that's right. My friend ran tests for two years and concluded that plants don't absorb more than 32 mg/L. So giving them more than that is an unnecessary electrical expense. He also concluded that providing pure oxygen generates much higher growth and yields, practically as if they were receiving additional CO2.
It's a shame I didn't have the oxygen concentrator at the start of the crop; everything would have gone much faster, but I'm already well prepared for the next crop. I'll also have to buy another pump to give me a little more pressure, since the nanobubbles currently enter at 32 psi, and anything higher would be better. I made a few mistakes in this crop, but nothing serious. I promise the next one will be perfect

I'm already recirculating the water, for now using the same low-pressure mistblowers with a 400 L/h pump, but in the next one I'll install other diffusers that send the water directly downwards without spraying the roots. For now, I've placed the inlet on the same mistblower manifold with a non-return valve, and I'm currently programming it for 15 min/h so the nanobubbles are at the bottom of the buckets and the water is renewed.

Ok sweet, a inline UV filter would be an added bonus and easy for you to add with this dope setup.
On another note, I wanted to experiment/research inoculating the root mass/system with AM Fungi.
i know how it works in soil and mediums, but I'm still content it can offer a benefit In HPA, like contributing to root mass and being a "safety net" , a barrier on the roots against other pathogens.
I suppose if a system is sterile enough it's really not needed, but I still feel there's benefits to mycorrhizae in a HPA environment.
Something I'm trying to experiment and research.

Plants look great, can't wait to see the next run with the concentrator at veg, are we sure we are conclusive on 32mg/l? I wanna see 40mg/L
Otherwise, if 32mg/L is around the theoretical maximum for a reasonably sized Budding female, and needing/wanting no more, that's great.
I've been looking for this answer, thank you and you're other friend for their research results Data.
I'd have to go back and check but I think a different forum member ran up to 60mg/l with no negative affects, again, don't quote me on that, I'd have to double check.

You're doing a great job. If you're excused, I'll stay and see how it goes. I find it very constructive and informative. We're still doing some last-minute tests with the generators to gather as much information as possible. For now, I can comment:
-In coco coir, I've used 32-34 mg/l of dissolved O² without any problems.
-In aeroponics, I'm maintaining a constant level between 15-20 mg/l, as I also recirculate 24 hours a day, and much of the O² is lost during this process. Therefore, I believe that increasing the O² further may not be very energy efficient.

I'm using hypochlorous acid in the system, so the microlife issue would be impossible.
I've asked the creator of the generator about nanobubbles. I hope he'll join the group here to better explain his tests and theories. I sent him the link to this post, and yes, I'm wrong about some things. I'm looking forward to him joining so he can offer better reasoning than mine.

@rustlessbiscuit @Ca++
@Sr de la luz Meet the creator of the nanobubble generators. He'll be able to explain them much better than I can. I'm just a tester of his great invention
Sounds very interesting.
What differences can you observe in a grow compared to your grows before the nano-bubbles?

The point of aeroponics is to use the atmosphere for oxygenation of the roots. Cycling the sprayers gives time for the roots to breathe.
Are you adding oxygen to the water or to the root zone?
I could see adding oxygen to the atmosphere to be extremely effective; if you are oxygenating the water do you have a side-by-side trial showing that it works against a control?
I’m intrigued since I’m planning a hydroponics setup for winter to offset the lack of humidity while using soil during the summer to prevent high reservoir temperatures.
Cheers!

There are several benefits I've noticed, and although I haven't done side-by-side testing, I have noticed several benefits from using them, such as:
-Increased root growth
-Better nutrient absorption and transport
-Improved growth/biomass
-Apparently better flavor/terpenes and potency
-Less salt buildup in substrate
-Improved aerobic microlife
-Cleaner irrigation system
It's possible I'm leaving something out that I don't remember, but these would be the main benefits of using it. I thought I read that someone was using very high levels of O² in fogponic. I'd be happy to share information with that person honestly. Regards

It would be interesting to collect water from the emitters, and see the dissolved oxygen levels the plant see's
One issue with high levels is that they deplete with little effort. Mist that water, and I wonder how much leaves into the air.
Plant results look good though. Great even. Perhaps lost oxygen during atomisation isn't really lost anyway. The container is a seal environment. Like a bomb though. I have my concerns, that warrant hiring a gas analiser.

A member on another forum, 90mg/l with o2 concentrator, fogponics.
He got up to 300% atmo, but I'm not sure what he ran the plants at.
I can message him for ya and see if ya want
good to share data.

We use Athena Cleanse. But my friend @Sr de la luz also has a system like yours that creates hypochlorous acid.

Good morning friends, yesterday we had some complications with the power in Europe, but luckily I managed to save the girls this way. I had two batteries in my electric drill charged and I managed to spray at 1 bar of pressure every so often until the batteries ran out. I continued spraying with the hand pump until the power came back on. The girls were without power for 12 hours and in a few hours the lights came back on. Crazy, friends !!! I have friends whose lights have shorted out and broken. Luckily, my electrical system has a surge protector and nothing was damaged .
When the equipment is turned on, I have to perform EC correction since the plants don't tolerate it. I followed the Athena table, but they don't tolerate 2.5 ms.

So the UPS is in the post then?
I bet they just increased in value, and price.
Mines not actually installed, and there is really no excuse for it. I have an inverter for the car to. Somewhere.
CB radio to.. and while I know it won't happen... well it just did, so it does.
Frigging nightmare. I hope they can tell us what happened soon.

Glad you’re making due. Stuff like this is why I stuck with flood tables instead of going aero when I tested it, numerous times.
For me the benefits of aero were outweighed by the fact that the best setup ever can be all dead plants in a few hours if a problem comes up.
