I recommend 3%
why? I’ve experienced with it many times.
Also promotes root growth.
The 3% has stabilizers in it and isn't best if used often. If it's to be used for treating root rot in hydro you would have to use 11X as much as you would if you used food grade 35% which is pure H202 and water only.
For instance: A tall Rubbermaid tote holds 50L with pots installed and if I got rot I'd want to use 4ml/L of 35% so 200ml. With 3% I'd need 2.,200ml or probably 5 drug store bottles worth. It would be a lot more expensive considering a 4L jug of 35% cost $65 last time I looked. I bought a 1L jug at the health food store a couple months ago for $18.
I'm on the fence about that.

Same thing with ISO at the feed store. Was lots a couple weeks ago but all gone now. I just got a new litre of 35% peroxide a couple months ago and haven't even opened it yet as I still have about 250ml of the last one left. Got a fax machine so I can send you some?
Some guys use bleach and even pool shock instead of peroxide and it does work but you'd have to do some searching here or on the web for how much to use.
Maybe just snip the bottom 1/3rd off the root and get it in a pail of nutes. If it survives it'll grow lots of more roots fast. 300 - 400ppm or so is good for her atm.

you might want to experiment yourself.
i used many clones to experiment on, I’m pretty accurate. I’ve almost killed some and brought them back from the grave just to see what happened
When I was doing flood and drain I used good old chlorine bleach in the reservoir. It never hurt the plants and kept the rot away. Commercial hydroponics growers have been using it for decades.
Waiting for the gasps from those that think I'm crazy for actually adding chlorine to my grow.
I know it works but the chlorine in bleach forms chloramines when it reacts with organic matter like anaerobic bacteria which is what you're trying to get rid of. That's what makes your eyes red in public pools, not the chlorine itself. Other organo-chlorides are formed too and chlorine itself is a known carcinogen. H2O2 has none of these issues.
Not that it's going to hurt the plants any unless they absorb excess chlorides.

You seem to know more about the science of it than I do. But it worked keeping rot away using about 4 ppm's. There is also chloramine in the tap water where I'm at. The levels of chlorine or chloramines in tap water are not high enough to do any harm. To this day I still use tap water straight from the tap. I even water outdoor plants in pots with water straight from the hose and I've never had any issues. Plants grow healthy.
I did use 35% H202 for a while but bleach was so much cheaper and it doesn't burn like that industrial strength H202 if you get it on your skin. Don't ask me how I know.

it's true that all commercial H2O2 has stablilizers, but food grade is difficult to find locally and ships with haz mat charges.
