Cannabis and o2 in the rootzone

I'm listening.

Here is what I have tried:

O2 at different rates:

55% @ 3lpm
65% @ 2lpm
90% @ 1lpm

Injected via powerhead venturi
Directly bubbled

I have always had leaks. My new system is much tighter. I still need to test but the big fog tent was not really that high - like 60% was all I could reach even at 90% over a long time undisturbed.

The cloner on the other hand I was pumping that full. 300% atmospheric. Wowza.

In terms of DO water out of the RO tank is between 7 and 8 mg/L. I was getting mid 20's in the cloner.

Results are impressive.

Have you seen my fog setup? What would you try to change on the delivery?
The only thing I can maybe add to that off the top of my head would be a stone instead of direct into the venture. It's possible the correct stone size might help your rates some more


There not terrible expensive either to try a few different options

Sounds like you're input volume and the reservoir size is the main factor here. But fine dispersal could be a part of the puzzle 🧩 also

Lol 😆 pressure might can be a big variable, possibility. If it's even feasible...

Makes me really wonder 🤔 just how far it can be taken and what might be possible

An approach like that has all sorts of measurable implications likely. Ie like a lot less fertilizer requirements for instance

So it might have scaling potential. Wouldn't it be really cool to invent something that could be used for improvement AG in general. Industry wide

Pressure to keep the the o2 in

(?)
 

NASA studies this kinda thing. 😆 it's classified

Pump those buds up.... I want them them the size of a 👊.
Yea, I can't get much info on nasas stuff lol

All I know is, Bruce bugbee did a lot of the old research for growing plants in space, afaik.
And utilizing aeroponics.

And bio-control chambers is the proper term and they are patented by NASA, afaik.

Stuff is super important for colonization of other worlds.

There is not enough pressure from a concentrator to drive a stone. It would require an in line air pump.

I am currently running the hose thru aquarium bio media and bubbling thru that.

Yeah leaky big spaces are the problem. Or I need a bigger concentrator. Trying fixing leaks first.

We did look at pressure before I decided on fog. I still have all the parts here waiting for a pressurized aero setup. Fog just seemed logistically easier. I still think that personally.
 
I wonder why just 2? Different strains?
4 different strains but it may have something to do with how I set them up. I may have had too many clay balls on top of the dome or not enough and dirt plugged the air off. I've taken more care this time and they should all be consistent. I'll either get more roots or less then I can learn from it what works better. I think the domes and air stones have shown me it works, now to get them all working the same.

I've relapsed, my sickness came back Thursday I was in bed all day, yesterday not much better, today I'm at least up and moving around. It felt like a mini version of what I had the first of the month, really achy, nauseous and zero energy.......fkin bugs !!!......I won't be on here much while I'm recuperating......again...its hard to read and type feeling like shit.

Sorry cuz. I know how that sux. Feel better.

And yeah. Your setup would be interesting to pump O2 in there vs. atmosphere. Those roots would love it.

Yeah not enough pressure to use an air stone because of the design plus the volume is much lower

Yea this can be used to separate co2 and use it also. It vents co2 and N and then pushes the o2 out the feed line. So you could separate concentrations theoretically taking air that has been breathed and removing the co2 to feed to plants in a space shuttle while returning the o2
 
Correct 💯 this is the term actually. It's complete control over all the variables


I think it could be done by creating a positive pressure chamber which wouldn't be really difficult... Just need extra air input to keep above the leaking rates and good filtration method

Then a barometer to dial it in to a threshold. I highly suspect no more than 1.5 to 2 ATM would be warranted

Yeah I seen after my first rant that you're kinda selected fog for it's method strength. I think you're on solid ground doing what you're doing right now 🤠
 
The best example of physical relationship between temperature.. pressure and gas...

Opening a warm near 🐝

I have some suspicion that this could be tied in the nutrient transmission pathway. Pressure could enhance photosynthesis . Can't say for sure but there's some logic I believe

Oxygen is for sure

That's genius
Recycling the air we breathe out in a shuttle, filtering the CO2 into the chambers.

Thanks for the interesting thread @Aqua Man, and thanks to everyone who contributed. I'll be thinking about how oxygenation could apply to organic soil growing. I spent some time scanning web search results. Information is plentiful, so it will take some time to sort and sift through it.

Apparently, there are time-tested techniques for increasing oxygen in soil. One is structuring the porosity of the soil to make sure sufficient pores exist in the soil to provide oxygen for respiration. Excessive water also limits the amount of oxygen the pores can contain. A common method is to loosen the surface of the soil, which is known as tillage aeration. I noticed hardening of the soil surface can result from top dressing nutrients and amendments, so I use a hand rake to till the soil.

There's abundant information about using H2O2 to oxygenate soil. It is a powerful oxidant. It reacts with water to release oxygen molecules. I need to read more about this, especially techniques for how to do it. I noticed claims that too much oxygen can stunt root growth. It's also a disinfectant, so I began to wonder if it could be used to sterilize soil prior to the addition of helpful microorganisms and growing plants. If nothing else, it's commonly used to kill fungus gnats.

The premise would reinforce why weed grows really well by the ocean also...
Then mine should be growing well. I live on an island. There certainly is plenty of vegetation here.

Where did you find to much o2 can inhibit growth. Thats just absolutely false so you know. To much h2o2 i can see as it damages root tissue. To much o2 in a sealed room can inhibit growth but thats in the atmosphere not the root zone

H2o2 is just not a sustained source for o2 enrichment…. Its extremely short lived and wouldn’t put it anywhere near an organic grow. Imo h2o2 is a terrible thing to add to soil

So let me explain a bit deeper because it will make more sense. Plants use o2 in the rootzone and co2 in the atmosphere. The lrease them opposite so release o2 into the atmosphere and co2 into the rootzone. High levels of co2 in the rootzone or o2 in the atmosphere create problems for the plant.

High levels of o2 in the atmosphere can affect the efficiency and ability of the plants to take up co2 and vice versa in the rootzone.

An o2 concentrator wins 2 fold because its separating the o2 and co2 to deliver then where the plant uses them. O2 goes to the rootzone and co2 goes back to the atmosphere with less of the antagonists in each area.

A concentrator will not build up a room to dangerous levels as its simply separating the gases and they will blend again when expelled as if not ratios have changed except the fact it delivers the gasses to where they are needed by the plant the most. This may not make sense but i can elaborate if anyone has questions on this

I haven't had time to read about it in depth. I've mostly just scanned search results and read some of the summaries.

I'll post more info when I can.

I suspect that might depend on the method of application and the dilution. I found many recipes for mixing H2O2 with irrigation water. It's also useful for pest control. I do understand the issue with organic growing, however. I mentioned the possibility of using H2O2 for soil sterilization prior to its use, which only occurred to me as I was composing the post.

When I find more info, I promise to post more.
