Has anyone ever used an oxygen diffuser like o2grow. And do you have comparison pics, reg pics, and or links to a grow that does?

Its BS they tried to use it the aquarium industry and when people caught on to the false DO readings and the reaction of the emitter plates breaking down in saline solutions i guess they moved to hydro to try and make some money

I would like to try dwc, but airpumps are way too noisy for me.
Don't skimp on the price of the pump and that's not as much of an issue. You can be standing a foot away from my pump and you would never even know it was there because of the way I've isolated the vibrations.

I have an O2G 2020, but due to other issues that caused 4+ grows to get root rot and die, I have not been able to try it

I finally have the problem sorted and will employ it in one rez next grow

That said, I have my doubts that it will significantly outperform my newest DO generating technique

Over the years, I have studied structured water's impact on plant growth and how best to incorporate it into my rezes

In the past I was using a 260 gph pump with a tall riser and 2 elbows so the water would aim down into a large net pot that was above the water line, filled with stones. As the pump cycled; between the splash and cascading nutes through the stones, plenty of DO was created, but I thought of a better way that I can use in a shallow rez. My first attempt is in my 2 gallon SWC (shallow water culture) tote, which I typically use to start seedlings/clones, I decided to try a horizontal approach. I took a 1 liter plastic bottle drilled a bunch of small holes then half filled it with a combination of platonic solids (do a search for why them) + some small marbles, both of which have to do with structuring water. I then attached a 80 gph pump to the mouth, laid it down sideways, and put it on a deep cycle timer at 3 minutes on and 60 minutes off, The holes must be drilled below the water line or else they will spray like crazy.

To be safe, this grow I am also using a 4 head air pump 24/7, though it probably isn't needed. Will try one tote without it next grow. Well, 3 now that I took clones: one air stone is inside the DIY cloner

Since taking these pictures I removed the large fan leaves below the ones at the top to provide more light to the many side branches

the ones with the fins sure air and they run hot too
The fins have nothing to do with the noise, they're there to dissipate heat. Ensure that you have plenty of output for the pump size and reduce vibration transference -- it's as simple as that.

This is a 1110 GPH pump sitting on 2" foam to mitigate the vibration. I am only using 2 air lines with a large 2x4 airstone on each line, this is enough to reduce backpressure on the pump itself. The lines are under tension to keep the manifold from touching the ground which makes noise. There is a fan above the pump to keep it cool and balance the temps in the reservoir chamber.

When the 1/4" sliding doors are closed you could not tell there is a pump running, even if you were standing right next to it.
