New oxygen technology in RDWC DWC pot grows

[J Henry]

But you've got the cathode and anode at the bottom with no membrane barrier so it's not JUST 100% oxygen and hydrogen, it's also ozone and whatever other gaseous byproducts of electrolysis are created when you run electricity through nutrient salts. Ozone is good, since it's more soluble in water than pure o2.



Henry's law states that you cannot increase saturation level above 100% at atmospheric pressure (not even taking temperature into consideration). If you're measuring dissolved o2 in the water right above your overpriced equipment then you're doing it wrong.

I can get the electrodes you are selling from china, and they're much larger and way cheaper for what you get. How you think you can get away peddling a switch-mode dc power supply and the cathode anode assembly in molded plastic for as much as you are is beyond me.

I guess it might be convenient for some people?

Just to be clear and avoid any misunderstanding, Henry says, "At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid." You might study up a bit on this. And you're absolutely correct, the average American does pay very well just for convenience.

Pure bullshit.
Just make sure not even a single light beam goes through the pot in your bubbler, specially through the net pot.
Wrap your bubbler and lid with a foil/bubble insulation, even if it's black.
Spray a bit of Trichoderma over your roots twice a week, if you can add some Mycorrhizae and Azospirillum it'd be a great add-on for your plants.
NEVER EVER USE H2O2 IN YOUR WATER CONTAINER.

Never had a chiller, frequently hit 80ºF, never had any fungus...

And that's it; try it out before coming back with some BS internet stories.

OK

Thank you for not responding.

No, I'm pretty sure he does mention something about temperature and solubility. So you might want to study up a bit on this.

Do you even understand what the part in bold means?
Let's use a bottle of Coke. When it's new and sealed, the gas pressure above the liquid and in the liquid are in equilibrium. Once you open the bottle, and expose it to atmospheritc pressure, the gas pressure above the liquid drops, creating an area of partial pressure of the gas in equilibrium with the Coke, meaning the pressure outside the liquid is less than the pressure of the gases dissolved in the liquid, allowing the supersaturated CO2 to escape the liquid.

Now answer my damn question, charlatan.

Yes, there, something about temperature and partial pressure of the gas here.

 

[J Henry]

OK, 1 more time, now really try to pay attention this time.

In a mixture of gases, each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the volume of the mixture at the same temperature. The total pressure of an ideal gas mixture is the sum of the partial pressures of each individual gas in the mixture.

Can you guess or determine what the partial pressure of 20% oxygen is when the source is gas mixture is air? How about 159 mm/hg or so at sea level. Now it should be easy for you to see the oxygenation problems with air.

Oxygen levels are important in preventing root rot but temperature is just as important.


A water chiller is safer than "adding more oxygen"

 

[KryptoBud]

Nice sales pitch..lol

300 bucks for the 20 gal capacity electric fly swatter
Do you believe J Henry is a shill...yes!

I think he's waste of oxygen personally.

 

[Rrog]

It's crazy ridiculous

 

[Tripp2005]

Hydroguard works way better 30 bucks a liter

 

[J Henry]

It's crazy ridiculous

Great

We've been around hydroponic grows for the last decade. Over that decade, we have across root rot. Every single time it was directly correlated to a temperature issue over multiple days (water chiller failing).


The day I see someone get root rot at 68F with enough oxygen enrichment will be the day I change my opinion on that. That day has not come yet

I've had the snot looking clear slime develop in my systems even with chillers and plenty of aeration. Water quality differs from place to place and even people using RO have had problems. IMO, a good sterilization regime is more important than chillers.

You could very well be right.....Ive personally never seen it.

Browse through the hydro section threads...you'll see its pretty common.

I have got slime at low temps but never pythium. I run the lucas method and don't dump my res the entire grow. if I get a little slime I add h2o2 & wipe the sides of the res then filter the nutrient through a fish filter no active carbon for a day. slime stays gone for a few weeks or more. I keep my res temps between 67-70F I keep it insulated and use frozen water bottles.I found keeping crap out of the res works best. wipe the lid off before you open it &use a test jar so you can close the lid while you test.

and i'm a potty, potty mouth.

that about cover it J?

oh yeah, and he works for a company O2Grow that sells the equipment he is now trying to sell on here.

if this is true, can we lock this -ish

Just so we are all on the same page and have a clear understanding of what you are trying to say and what you really mean…

What exactly is your definition of “oxygen enrichment?”
