How do you oxigenate your reservoir?

[flylowgethigh]

This is easy to explain: Less than 20 ppm of air in water is sufficient, as can be seen in any DWC system.
Air, as mentioned, contains 200,000 ppm, which is 20,000 times more than what can dissolve in water.
In a substrate containing air, oxygen constantly diffuses from the air into the water when the roots consume the oxygen there.
In your case:

1. There is more than enough air in the bags,
2. The bags are unlikely to be hermetically sealed, and
3. I assume you open them occasionally for watering

Yeah, one of the bullshit claims why one should add h2o2 to the water.

This dose is harmless, but would also do nothing to your nutrient solution.


Ok, sounds all like a good setup for a dwc


And nope, you don't need a bubbler for soil^^

Bubbler is in the rez, not the soil. Maybe I didn’t mention I use a SWICK, but also top water when I feed. I like my water oxygenated. Now… If you were being some kind of know it all and saying I don’t need oxygenated water in soil, my opinion is the opposite. Plants agree.

Edit: After rereading the reply you wrote to my rainwater statement, I rename you Dr Dumbshit. Rainwater has so much H2O2 that you can smell it. That water is so much better for plants because of the free radical Oxygen. Where did I suggest putting in H2O2? I don’t suggest any such thing. Maybe to wet seeds.

Idk about the technical stuff but these were in autopots with the actual pot sealed around the top.

None of them presented any problems, I feed the others from the bottom aswell they've not been opened bar one for a look to see what was happening.

Do you know which plastic you used to seal them? It might be permeabel for oxygen. Then enough oxygen is available to keep the roots healthy.

Hey bud I used those paper thin plastic shopping bags available at most uk corner shops, the purpose was to keep fungus gnats in/out at the time I didn’t think about the oxygen side of things tbh.

Yea, it's easy to overlook such things. With how I understand autopots the bottom is always in contact with water so oxygen has to come from the top?

Those plastic bags are most often LDPE. It's very permeable to oxygen but has low permeability to water vapour. You can see the water condensing on the inside because it does not go through the plastic. Appereantly that supplies enough oxygen to keep your plants happy. The more you know.

Seriously, my friend? Free radicals are harmful to all organisms. A bit of basic biology knowledge wouldn't hurt if you're working with plants. But go ahead, keep giving them poison.
I'm out here. For those who are able to understand, all the information is available. And for those who don’t want to, maybe they’ll get to that point eventually. I had to go through that phase myself—H₂O₂ has only been used for cleaning here for the past two years.

 

[flylowgethigh]

Yeah seriously. Whatever you want to call the extra oxygen atom that rainwater and H2O2 has is called.

Look at it this way, I have a pond and we get feeder minnows to feed the stocked fish and also use the minnows to catch and release the fish on minnow day. I put them in a cooler with water, several hundred. In a few minutes they are on top gasping for air. Pouring water in the cooler to make bubbles and turbulence fixes it. I don’t pour H2O2 in the cooler, and don’t advocate adding it to the rez when water action works.

Guys like you who act like they know it all and talk down to people, usually don’t.

I don’t! Just a circ pump 24/7

Try not to make growing a weed harder than it is!

LESS IS MORE!

Do not worry about anything until you can control the environment like a boss

Nutrients are the least important part of the equation!

 

[Orange's Greenhouse]

I don’t! Just a circ pump 24/7

So... you do?

 

[LJ farming]

So... you do?

Maybe I don’t understand the question?

I run 200GPH/800LPH pumps in my 50g/200l reservoirs 24/7/365

I know it creates a bit more O but I honestly can’t say if it’s enough to matter. I run circ pumps to keep the nutrients mixed

I have run fish tank air stones as well they created nasty foam and donkey snot.

Aquaman on another forum explains how he adds O to the root zone with a medical piece of equipment that is not cheap. I am incredibly not smart enough to understand!

However IMO There is absolutely no reason to worry about it until you have the environment dialed! As well as light intensity, strain, nutrients, and the other 7000 variables!!!

My mad scientist has a blast mixing salts with a magnetic stirrer!

Merry Christmas all!

Peace

Hydrogen peroxide is nice. But too costly to use all the time.
An air pump is enough for most people.

I ran COCO DTW sterile with H202 for a minute or two!

In COCO DTW running LIVE increases the terps 3-5 times IMO

Again I’m just a beginner!

Peace

Hey LJ!
How do you clean the res and the system between one run and another?

In this run i didnt use any beneficial bacteria but im plannin to do nex run......
I really would love to avoid mess with bleach to wash everything out...prolly just wipe the res with hyd peroxide and then flush with water the lines.....

 

[Orange's Greenhouse]

flush with water the lines

That won't remove biofilms or precipitates in the lines. You can do nothing for the same benefit.

 

[Grapefruitroop]

I have a 120 micron filter and lines are all black....i think its better to flush away the nutrients that are sitting there for few days...
You dont do nothing specific to sanitize the res if there arent beneficials in it?

I dose peroxide daily and clean with fenton between runs.

 

[Grapefruitroop]

At which dosage?

 

[Orange's Greenhouse]

10-20 ppm

What up y all!

Bubbling the reservoir with an air pump and some stones 15 min prior to each watering event, yay or nay?
I also have a stirring pump that run togheter with the air pump.....

Its really easy and simple with this method i found ....and keeps the water clean, stable and can help cool the water some.....depending on your reservior size...ive done this with over 1000ltr reserviors....you shoul only need a small pump.....set the pump up so it sits at the bottom of the reservior....with a lenth of pipe atached to it.....you want the other end of this pipe to sit at least 6 inches above the top of your full reservior water level....now switch this pump on and leve it on constantly.....what you end up with is a fountin type thing were the water is constantly cycled through the pump and at least six iches above the full reservior water line and it constantly splashes in....its almost like a waterfall but on a smaller scale...this constantly agitates and airates the watter and keeps all of it moving and splashing together....if your pumps good and has good filters ( i usualy add some decent weight stones around the intake of the pump wich also act as a additional filter.....this is one of the most efective and cheepest ways i found after much experemantation and works better than most methods....if you test at a waterfsll that has a good drop you will notice the air levels in the water are realy high....also prevents any algee or other nasties ...very efective method...wen set up right and youve had the whole watering cycle going around afew times i found it easy to keep ph stable long term too.
