I am the proud owner of one of Warrenâs (Moleaer 25GPM) nano-bubblers and totally love it and what it does for me. I went ahead and purchased a high quality (YSI) D.O. (dissolved oxygen) meter to test the saturation, longevity and loss from the Moleaer system as well and learned a very interesting thing. I took tap water and measured the D.O. Then put in a standard air stone on a good pump and watched the D.O. actually go down! Crazy, right? True! Same results every time I show one of my hardcore air stone grower friends when I tell them to get rid of the stones. According to my YSI meter, theyâre actually decreasing the D.O. using air stones!

Scott, small world you are on the network. Awesome. Appreciate you sharing your experience and observations. Any chance I can get you to elaborate on what you saw in regards to plant health and development?

How does your product compare to Proxair O2 injector and water inline dissolving tank?

I would need about 5000 gallons an hour with high capacity at about double.

Howdy Warren! Sure. Iâm not a great experimenter (as you know), but I definitely see what I would characterize as higher metabolism. Theyâre more lush and vibrant (healthy looking). The root zones (I grow in rock wool) are healthy and white. In many cases the roots grow so well, the cubes (6" Grodan) get raised up off the tables by an inch or more. They grow faster and seem to process nutrients more efficiently. My evidence for nutrient efficiency is that my plants got greener very quickly at the same nutrient levels when the nano-bubbler was installed. Maybe the Nitrogen was processed or delivered better? I would also say that whenever we have unhealthy plants, for whatever and sometimes many reasons, they still tend âmake itâ to harvest and produce surprisingly decent flower quality. Having been growing commercially for over 9.5 years now, Iâve certainly seen my fair share of problems and made a large number of mistakes in my quest, but now with the bubbler my yields donât seem to suffer as much from errors and environmental problems. My reservoirs are definitely cleaner and I donât seem to suffer as many line and emitter problems as I used to. I could probably go on and on, but Iâve thrown away all my air stones and circulation/stirring pumps and would feel ânaked and afraidâ without my nano-bubbler. The Moleaer machines are just as Warren described in terms of simplicity, effectiveness and reliability. We easily achieve 35 to 40 ppms of D.O. (> 400% saturation) and itâs very stabile and long-lasting. Moving or stirring the nano-bubble water is the only thing that seems to decrease the otherwise highly stabile D.O. level. For instance, I can send 35 ppm water down a 100 foot 1/2 inch pipe and deliver it to the root zone at approx. 25 ppm D.O.

In fact, a lot of my rooms are on recirculating systems and we add a bit of fresh water (nano-bubble water) and nutes to them everyday and they still consistently maintain 12-15 ppm D.O. continuously which is 150 to 200 % saturation.

I am not familiar with the Proxair O2 Injector - did you mean Praxair?

Ethan, please can you clarify your question - you need to aerate 5000 gallons of water per hour?

My bad typo.

Praxair could oxingnate 5000 gallons an hour and 10k gallons at peak 50 ppm O2
About 30 ppm at the end of the drip line.

Fundamental diference is the oxygen transfer efficiency of the method of injection. Any O2 injection - either Venturi or High-Pressure has a low oxygen transfer capacity. Typically less than 50% at best. With a nanobubble generator, we convert that bulk gas into nanobubbles - since the nanobubbles do not rise, you retain almost all of the oxygen you inject. If you are injecting micro bubbles, most of the gas rises to the surface and is lost.

This was solublized oxygenation same as used in large scale water treatment plants just a lot smaller scale.
The oxygen could not bubble out or what good would that do?

Very familiar with the technology and their method of aeration. We work closely with their R&D team. Comes down to two key differences. Nanobubbles and dissolved oxygen (our system) or simply dissolved oxygen (injection method); and oxygen transfer efficiency (OTE). If neither are a priority, then there are many simple ways of injecting oxygen into water to elevate DO. We see distinct benefits in plant growth related to the presence of nanobubbles.

That answered my question.

@Moleaer This seems to be a great benefit. I know oxygen is the one thing that I canât really sell anyone and its the most important for plants. I canât wait to get your technology together with mine. We will then be completely digestible and constantly moving . Nice work !!

Kareen, our system is very easy to install and plugs into a 110v outlet. Depending on the site setup, some are much easier then others, but we would be able to walk you through it over the phone or meet at the site to get it done.
