Cannabis and o2 in the rootzone

[Aqua Man]

I wonder how much constant flow of O2 might affect temperature regulation especially 02 exchange capacity at high temperature ie 80+f or 26.66+c


On a side note I think it's actually cooling the whole thing while it's happening... Via a type of convection I think maybe. Not sure exactly

But should have some type of net cooling effects

Im not sure how it effects rootzone temp but i could see it possibly helping plabt temps through regulation of transpiration rates

This is the magic bottle neck in the bottom half of the plants IMO

Colder water would hold more oxygen right?

As there is less energy?

Yes but As more storage potential. Not less. The cool is good for this side of the biological battery

Energy coming mostly from the top of the canopy. Mostly but not all. There's (bio)chemical energy below but it's not temperature dependent like you think about above the plants... It's a cooler zone

It's why everything growing towards the light... It's all moving along an electron hydrogen gradient... Oxygen is the donor element

 

[Aqua Man]

The bags as a air cushion under the medium?

The bags creating separation where you can control the environment that the media is exposed to better

 

[Aqua Man]

Cold water holds more o2 yes. There are several implications to increasing o2 and part of that is the fact you will no longer be limited by temperature for the concentration of o2 that can be dissolved in water

 

[Aqua Man]

That means plants may like the temperature they do for many reasons one if which is o2 concentration so by changing the equilibrium in essence we may change the plants likes or need on water temp allowing them to grow in much higher temps as was my experience for a period my root temps were over 90f and averaged probably about 82f. Without the o2 concentrator i do not believe this would be possible

So are there any type of solar fogger mister I can make? They sound really efficient if I don't need to plug it in

I've got a few small solar pumps

They can be run off solar panels yep and pretty low wattage

Love it! So many ideas swirling around in my head from the education y'all are giving me!!!

Would it be advisable to set up a small water fountain, like the one Observer posted, in the reservoir for DO or are their better ways of doing that?

Trickle filter is one I absolutely live but not done in hydro yet… it’s probably the best option to do organic hydro. Scale of this filter is important

 

[tobh]

So with the increased levels of O2, what implications happen with the pH and the corrosiveness of the solution? Given H2O2 is effectively water with a boosted level of O2, and we hydro guys know how corrosive that shit is (eg, don't get it on you because that shit buuuuurns), are you effectively creating H2O2 in the res? Or despite the elevated concentration of O2, you're still not reaching the point where there's the chemical reaction to bind the excess oxygen to the H2O molecule?

Trying to understand the underlying chemistry that's going on here, or could potentially occur.

Can you go into more detail about this? I would imagine the longer the water is dropping the more DO is occurring?

I'll back up what @Aqua Man said re: venturis. Of the various methods for increasing surface area of a solution and maximizing DO, venturis have been my absolute favorite method. Almost nothing else compares imo

Look up henrys law. Oxygen as in o2 is not nearly as oxidative as h2o2 so no burn. It’s completely different.

H2o2 is extremely short lived and as it breaks down the extra o2 is released via gas exchange. This make it extremely ineffective for this use

Ot more do just better gas exchange keeping the water closer to saturation

 

[Aqua Man]

Be back in a few bit read up on henrys law and i bet it starts making much more sense. Easier to understand what im saying and why.. need like 15 min

I might try and do the airstone at the bottom of the pot vs oxygenated res with a waterfall to see if there is a difference.

This is what 34% h2o2 does to your skin

Feels like a bunch of microscopic needles.

Oxygen does not like to be a single atom. 2 combine together to make O2, what most people refer to as Oxygen.

It would take energy or a chemical reaction to split an O2 molecule into 2 O atoms which could then bind with H2O to make H2O2. That's not happening in our res. There just is no pathway for the chemistry to happen given the inputs.

 

[Franksta]

Thought these were kinda neat lol

This is what I'm working with. I've got a few more of them also

So what's a good way to setup? In a bucket or something else?

The stuff is in Solo cups with substrates right now hmmm

Connect it to your solution mix or create a chamber under the roots

H2O+ O2 isn't simply = h202. I think you're incorrect here

It might affect pH as you suggested but it's 02 gas in the H20. Not a formed molecule

hydrogen peroxide by electrolysis with sulfuric acid introduced the more efficient electrochemical method. But there are other pathways

man, when i first started using 34% i got large droplets on my arms and legs. big ass white ashy spots for days. didn't heed the warnings about how corrosive that stuff is and learned the hard way

that makes sense, appreciate the clarification!

you are correct in that thought. brain meats aren't firing all the well today, especially now looking at the two chemical signatures side by side like that

One caution on Venturis - they are not all created equal.

The ones they call venturis in the tiny aquarium power heads are not, really just a mixing spot where the water moving past the air entrance port causes a low pressure and "sucks" in some air.

These will stir the water and help with surface oxygenation, but do fuck all on direct water oxygenation. I've tested this multiple times because I did not believe it.

Real venturis like the ones used for commercial purposes have a high pressure zone on the output where the water and air mix under pressure. This is what causes DO to go up.


That is a proper venturi.

These are as effective as farting in the tub

Sweet thanks for the info

Yeah agree there's a lot of different types of strategies and methods deployable for efficient effect depending on the type of grow conditions

It's a wonder why farmers are not using these types of approach in low water environment

 

[Franksta]

It wasn’t lol but the plant did ok and were severely neglected… look at moes root porn it will be a much better example. I tortured those plants

What about the flowering ends?.... Was the bud solid and oily? Did you experience little to no heat stress or... What's it called... When the buds look funny and less dense

 

[Aqua Man]

Foxtailing nope had none… the over 90f water the water temp lol… not air whoch is absurd by most standards … i neglected the fuck outa the plants. They just seemed to take shit standing up…. Its hard to quantify but they just seemed almost bullet proof in some regard. Had crown rot from poor conditions and laziness but treated and recovered amazingly as it’s usually a death sentence. Short veg i think 3 weeks and buds as big as 2 litre bottles. In large part due to the genetic but i cant explain how much it seemed to improve health and recovery rates. Its just something hard to quantify
