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.

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!

So... you do?
