Oxygen To Roots

I have read so much about co2 being introduced to the plants but nothing about o2 to the roots except in the most passive ways. Why not pipe o2 enriched air directly into the root mass?

roots need oxygen, co2 is for the topside

Depends on your medium... If you are talkin Hydro, air pump and a micro bubbler in your nute tank works wonders

In soil a 1/4 cup of 3% hydrogen peroxide per gallon of water will work wonders for this. You will see a difference overnight and it is great for the soil microbes.
Happy Growing

thanks for the advice, I like the h2o2 but I thought





abf said the lower concentration ie: 3% had a preservative in it that is not good for plants but wtf I'll try anything. But really what I'm talking about is the fact that co2 is prescribed for the canopy in precise dosage recomended and injected with pure co2 for a specific purpose so why not pump oxygen rich and I mean real o2 and rich into the root system?

probably because roots need to be moist and that would dry them out

theres a guy on youtube who has airstones at the bottom of his pots of sunshine mix... he just started, so i havent seen the results.

a little off the subject but since it's my thread ...............when you say soil does that include coco? i'm using kind of a , well actually it's not kind of at all it is a coco base perilite rockwool cube mixture that seems to be working well. Outdoor grow, cana nutes la confidential. But i'm thinking about stealing my grandfathers o2 tank and pumping a little into the root zone. Also, I have been turning a trash can over my plants in the evening to get the 12/12 cycle going. that has worked AWSOME.

just got interesting but I got to go back later thanks guys

I'm sure that you would have to sepparate the two (o2 and co2) to keep the plant from becoming confused (you know how easily confused plants are ) but since mine are outside the o2 would just drift off into the either. I think it might be worth a try.

You don't introduce direct CO2 to the roots because it isn't necessary for root development. Like it was previously said, roots need oxygen ( which air pumps provide and hydrogen peroxide provides as well---it breaks down into oxygen and water) and the rest of your plant that is green and photosynthesizing needs carbon dioxide

Here is a link it gives some uses of hydrogen peroxide and if you Google it you can find countless threads mostly from gardener's forums but all there is universities being done on it now. Peroxide is really a nice little addition to any additives which you currently use in your grow, helps to oxgeniate the roots, applied foliarly helps to kill mold and fungus supplies oxygen to the plant which it also needs in the canopy area in its cell structures.

This is worth a try in your grow and the link is worth the read.

I don't want to introduce c02 to the roots, I'm asking for information about pumping oxygen into the root mass. Any studies on this? Surly there must be.

Careful buddy, h2o2 will oxidize and kill all your soil microbes. I wouldn't be spraying it on the leaves either. Maybe the 3% stuff but kind of seems like a waste of money. Plants don't need oxygen when the lights are on. They give off oxygen. They consume oxygen at night but not much really and it certainly isn't a limiting factor.

Oxygen in roots is great, anyone running hydro will tell you that. Pumping air into soil? Probably not.

Hate to disagree with you, you are correct plants give off oxygen but they also use it. The beneficial soil microbes also need the oxygen to live and breed, the harmful microbes are killed by oxygen. You just need to dust up on your botany a bit is all.

First off, thanks for the advice. It is apreciated.
I looked at the h202 link as suggested canafan and at 3% it just seemed way too expensive. The 35% seemed a much more economical alternative and I probably will be using it in the future. Don't see how you can selectively kill microbes with h2o2. That doesn't compute in my mind. Sorry about that. I kind of agree with ABF at this point and believe that it's best to grow only weed and screw the microbes at this point anyway. I'll leave the organic philosophy to my vegetable garden which is as organic as practical.
I wish I had some data or studies (whatever) on concentrations, periods of injections, etc.............guess I'll have to do a little sperimentin myself. I like that sort of thing anyhow.

The killing of microbes in the soil with H2O2 is simple really there are aerobic and anaerobic microbes in the soil the anaerobic (sorry about spelling today had a slight stroke yesterday) are poisoned by the air they live in the soil when there is a lack of O2 and are usually pathogens to the plant and other beneficials in the soil. The aerobic microbes are the critters which are beneficial to the plant and soil. They are invigorated by the extra oxygen thereby breaking down the soil and nutes therein to feed the plant.
The expense well, in the states the cheapest place to buy it is probably beauty supplier, and they no longer sell 35% in the US because it can be used in explosives. Here are a couple of links you can look at, there are many more studies and forums which talk about the benefits and drawbacks, I am not trying to sell a golden bullet or anything just something that over the years I have added to my regular routine in the garden and grow room.

Is it really necessary to pipe O2 to roots? After a billion years u think plants would've figured it out themselves?

Ok, not to get into some biological pissing contest, I must point out that you are incorrect on a number of your assumptions. The first being that h2o2 only affects anereobic organisms. H202 is toxic to a wide variety of organisms, both anerobic and aerobic. You need to know what Hydrogen Peroxide does to SOME bacteria. It is, for some bacteria, considered as a metabolic poison, which kills them unless they have the enzyme catalase.

Hydrogen peroxide is NOT SPECIFIC, meaning there's no exact way to say that this or that organism will be killed by hydrogen peroxide or not; some organisms, aerobic or anaerobic, can withstand hydrogen peroxide and some cannot. The only way to know is to do the Catalase test (hope you know what this is). Catalase is the enzyme that some bacteria use to catalytically cleave hydrogen peroxide into water and oxygen...so, no hydrogen peroxide, no death to the bacteria. Again, hydrogen peroxide can affect any bacteria, whether they are aerobic, anaerobic, or facultatively anaerobic--there's no way to tell how unless you do the catalase test. The only ones not affected, in general, are the ones with the enzyme catalase.

With respect to the anaerobic bacteria not dying, well, there are a number of reasons. Some "anaerobic bacteria" are just aerotolerant, meaning they can live with air, but only in a certain partial pressure of oxygen; some anaerobic bacteria are not really anerobes at all because they are actually facultative; and anaerobic bacteria do not necessarily die that easily once exposed in air--however, if you grow/culture them in the presence of air, they surely will not grow.

So if you are spending money to inoculate your soil/ hydro garden with beneficial microbes and fungus..and then dumping h2o2 on them, you are in effect wasting your money. While 3% hydrogen peroxide is pretty weak in terms of an sterilizing agent (and as an oxygenator for that matter) it does technically increase oxygen levels for a short period of time.

The other big error is the assumption that 35% peroxide is no longer available. Ummm, have you been in a grow store lately? I bought a gallon bottle of it last week. I use h202 to treat my grow medium between cycles. I use high concentrations of it to sterilize my grow medium. It is a very common hydroponic practice to add 35% h2o2 to your reservoir if you can not maintain proper temps below 72 degrees. the h2o2 will add oxygen levels and keep harmful bacteria that grow above 70 degrees at bay. These people are effectively growing in a sterile environment. This takes some of the advantages of beneficials off the table but also eliminates the risk of root pathogens hurting your yields.

Again, your roots need oxygen for sure. If your growing in soil then I would suggest just running a courser medium, something that will allow for better gas exchange. I really don't see how you could get oxygen pumped into a soil type medium to dissolve in a efficient and effective manner. If you are not overwatering then your oxygen levels should be fine.
