Hydrogen Peroxide (H2O2)

-just the common stuff you get at the grocery store.

*I am using a mixture of several kinds of potting soil (Fox Farm, Roots Organic, local nursery brand, etc.) in 3 gallon cloth grow bags in a tent under full spectrum LED light.



I have been doing this for every watering since flipping to flower...

I take 1/3 cup of the 3% diluted H2O2 and mix it into a gallon of filtered water.

I place the 3 gallon grow bag into a 5 gallon bucket and water with the gallon of solution.

I let it sit in the bucket of solution for 3 minutes or so.

The plants seem to be responding well.

Has anyone else tried H2O2 in your grows?

you're not worried about killing all your bacteria in the soil?
Actually, I thought about that...but I wanted to experiment, I guess. So far the results are looking very good. I guess the experiment might end up being whether or not the extra oxygen is more beneficial than the bacteria it kills. If I had noticed any kind of negative reaction to it, I would have discontinued it. Before I started this experiment, I had some gnats flying around. Subsequently, they are gone, too. I'm keeping a close eye on things...but yeah...so far so good.

i'm not a dirt guy but would an airstone buried in the soil do anything? only run it just after you water them??

I guess if you are using synthetic food then it will probably help. Other then that i cannot see the extra o2 outdoing the microbial life in there.

Yes, this works. Its not quite what the "o2 freaks" are looking for but it helps a lot. When i went on my first 100% organic venture , it was a dramatic fail so some of the plants were stuck not eating or drinking so i had to add the airstones to the soil to keep them from rotting. the extra air just helped dry them out for me so i could feed/water again.

it contains phosphoric acid to stabilize it
probably explain the conductivity readings
the brand i use also lower the ph
That's weird...I just did a pH test with my amended water and it tested around 6.8. So, maybe the brand of H2O2 makes a difference?

I use 5ml per gal of 34% h2o2 in my Rez...why fight bad bacteria with millions of beneficial bacteria soldiers when you can just Nuke em

i think you'd be better off not using the 3% stuff with all the preservatives and step up to a higher % w/o all that stuff in it. you'd have to adjust your mix rate though.

Well, it's just an experiment and I'm just going with the stuff I already have on hand. As far as preservatives. I guess if it's pure enough to use in a human mouth then it's probably just fine for the roots. And, as of today, there is pretty good evidence that the plants responded to the treatment. The response was mostly positive, but I hadn't been pH ing my solution and I was a bit on the high side, so I got a bit of yellowing on some of the older fan leaves. I swear though, resin production has increased since the treatment. Fungus gnats are gone, too! At present, the soil has exhausted its nutrients so I have gone to water with a bit of 10-15-10 liquid fertilizer, some epsom salt and a small amount of cal-mag. 2-3 more weeks and go to flush...And I will continue to flush until the flowers are almost too ripe and mostly amber trichs on them. I've always cut them at the milky stage in the past, but I want to see what going an extra week or two might do. Anyway....

...yeah, I don't think I'd use H2O2 on a regular basis, but, as a boost for tightly-rooted pots, it seems to have worked. Chalk it up to another experiment that didn't end in a complete disaster.

Air stones and H2O2 are not going to be the best things for increasing O2 to the roots.

Try simply water/feeding the right amount everyday - To carry over till lights on the next.

Now that's increased O2 to the roots. No injured bene's either.

I've never tried air stone, but I did recently see a video of a newer growing technique that involves a hybrid between soil and hydroponic where they place an airstone under some rocks in the bottom of a pot and then fill the rest of the way with potting soil...saturating the soil (basically until it's mud). The soil is so saturated that the air generated from the airstone actually "boils" up through the mud. The idea behind it is to be able to get the organic benefits from the soil, combined with the accelerated growth characteristics of hydroponics -without having to use synthetic fert. I dunno...haven't tried it...but I am definitely curious! :)

But, hey, I tried the H2O2 experiment and I'm here to say that I didn't kill anything! :)
