Bro, I've added as much as 16oz. to a gallon of water and it didn't hurt the plant. All it is, is H2O(water) with an extra Oxygen molecule. I've done it with ALL of my grows and NEVER, EVER had the slightest problem what-so-ever. Didn't fuck up the ferts or cause the plant to lock out anything. Just my experience with Hydrogen Peroxide. Good luck!

Are there 10 liters in a gallon?
I think recently saw a reliable post that implied this wasn't for soil grows, as it kills the good stuff (microbes, etc) along with the bad bacteria?
Good luck.

There is 3.78 L in 1 gallon.

there is really no need for it ...unless you are having oxygen problems

I have only ever used it [9%] to kill bugs. Once that extra O molecule oxidizes and splits into water, the bugs don't like it. Becomes anti-bacterial too, in some cases.
It likes to kill certain "living" things, I would tend not to put it into soil if at all possible. I used to use it to clean hydro gear.

Hydrogen Peroxide is used as disinfectant. I'm inclined not to use it in soil.
OTOH: it's one of the more natural, least toxic sanitizers. I can see how that unstable oxygen molecule could be like bubbling nutrient water to promote aerobic bacteria (discourage anaerobic). It would be interesting if a chemistry student did a test of growing soil to see how it affects "the herd."
FWIW: I soak seeds in 0.5% to germinate. I think it kills any bugs on the shells, and the unstable oxygen molecule causes pure air bubbles to attach to the shell -- reducing the possibility of drowning. That's 5 parts water to 1 part 3% Hydrogen Peroxide.

I run DWC hydro, the only time I've ever used hydrogen peroxide, is when I had root rot.
However, I cured root rot by lowering reservoir temperatures and eliminating all light entering the buckets.
When I did use Hydrogen Peroxide, I normally just squeezed the bottle so it gave it a "shot" or two in to the bucket.
It helped a little, but, it made the PH fluctuate WAY to much.
I solved the problem by using the already stated remedy of lowering temps and eliminating all light.

I use 2-3 ml/lit of 3%HP every watering.My plants have never looked better since i started using it.I grow in coco,with no microherd to worry about.I found this link that suggests using HP in soil is not all bad http://hubpages.com/hub/Hydrogen-Peroxide-for-Plants
For fungus gnats i use 3%HP diluted 4-1 with water.
HP is supposed to dissolve salts,and ive found i dnt have to flush so often.
Tbh i wouldnt like to be without it now.

I'll have to try it once I settle down a few other variables I'm playing with. I'm intigued with your experience that it helps release salts. (I've been dealing with acidity attributed to the nutes I use.).
I grow in Pro-Mix (soiless). Are you sure we don't have to be concerned with beneficial microbes? I use Liquid Karma, Alaska Kelp and finally molasses in flower (which is supposed to feed bacteria). And then there's myco in Pro-Mix.
I'm willing to believe peroxide could be beneficial as a supply of oxygen to beneficial bacteria. I can see how that's possible. But, I'm skeptical that even soilless growers like us don't have those bacteria(?)

Usually i have to flush after 5-6 weeks,but my latest grow i let them go for 10 weeks without flushing,even then there were no lockouts,i just thought it best.
So im assuming that HP does help to dissolve salts,as it said when i googled it.
I grow inorganic so im not fussed about bennies in my coco.
In your case i would be wary about using HP,as it is a fungicide,so not myco friendly.
Do you add dolomite of lime to your promix?
