I'd get the peroxide. Lot of guys use pool shock instead but chlorine is nasty stuff where peroxide is just water with an extra oxygen molecule attached. It's that extra O that oxidizes anaerobic molecules like rot and will hit that before it attacks living tissue like roots. Chlorine is more indiscriminate and tries to kill everything. Some of those radical O atoms attach to other ones to make good old O2 like we breathe and the plants like around their roots so it's all good.

If you get any strong peroxide on your skin just wash it off right away and only the dead skin cells will be harmed turning that patch white for a short time. Wear eye protection! And don't use the 3% the drug store sells if you can get the food grade stuff. It has preservatives in it that may or may not be detrimental to the roots. Highly diluted peroxide breaks down quickly without them but the strong stuff stays good for ages.

Just so we are clear..What’s the correct strength of peroxide and what’s the correct ratio per gallon?

After considering all advice, I’m thinking of completely changing out all the water, adding 400ppm of fresh nutrients, and correct dosage of H202. Bring water level up to submerge basket for 3-4 hours. (Should be roughly 15-16gallons)

Then dropping level back down to about 1 inch below net pot. (12-14 gallons, where level is currently)

Anyone feel free to chime in and let me know if there is anything wrong with trying these steps.

I personally used 3% peroxide straight through the net pots to flush roots. But must be prepared to change out all res water and nutrients right away.

With 29 or 35% you want 4ml/l or 16ml/gal to get rid of root rot. Just 0.5ml/L or 2ml/gal for regular maintenance. 4ml/L is only 0.4% so it's not going to gobble up the roots and one dose won't be enough to do the job so daily for about 4 days.

I assume you can take nutes out of your rez for pouring through the net pots so do that rather than raise the level. I would recommend doing a nute change like you plan but skip the fungicide and maybe aim a little lower like 300ppm. Any time I have sick plants I cut back on the feed and light a bit so they aren't trying to veg harder while healing from whatever is ailing them. Easy enough to add a bit more nutes to raise the ppm once they start showing improvement. Just add teh peroxide and let it circulate for a bit then take out some nutes and pour it thru. Just have to do each one once a day after a fresh dose of peroxide but it won't hurt to do it a couple times especially for the first couple of doses.

Doesn't take more than a few days to start seeing new white roots starting to show up. I've walked quite a few people thru this and never lost a one yet. If you get 29% it won't hurt to add another 10 - 15% to the doses compared to 35%. I've used both.

No. You want that peroxide in the nutes to kill the pathogens on them too. You also need 11X as much peroxide using 3% compared to 35% to do any good. At those levels the preservatives in 3% will most likely cause problems of their own.

Proof is in my pictures. Flushed with 3% peroxide only, then change out res and nuts.... Plants look very happy now.
Proof? Of what? Why did you treat them and where's the Before pic? How much 3% did you actually use and how big is your tank? If you had a real case of root rot one dose of peroxide isn't going to fix it so are you going to change nutes every day if you have a real case of rot?

I've been at this a while and beat rot every time.

Sorry, no before pics. Treatment for fungus knats... Worked very well. Pictures proved that. No main res, but yes I change my nuts every two weeks.

Not sure on exact amount of peroxide used but I poured it right on top of the clay and roots heftily before changing my nuts in the DWC....

Im not as experience as you with h202,only thing I know for sure is when I did 1ml/g in rdwc I had to be careful and add it slowly ,if I didnt my plants would wilt immediately.
So your saying 16ml/g? of 29% thats 16x more than what Ive done.You're sure? Perhaps maybe just a dip for 20 seconds then rinse?
I just cant wrap my head around that strong of a mix.

Couldn’t find any locally so I ended up ordering this. Free shipping and should arrive after a few days
Hydro stores should have it,also a taxidermy shop should..Anywho good luck.
I have a bottle of Enzymes Komplete that I keep around.Its killed root rot for me in 24hrs.

I have been thinking. In the meantime while I’m waiting on the 34% h202 to arrive maybe i can grab some bottles of 3% to hold me over the next 3-5 days. Any thoughts?

Cost yeah a fortune,but yeah you could pour some through the net pot while you wait.

I’m using southern ag. I’ve been adding 1ml/gal everytime water is added or changed
you could easily cut that in 1/4. .25mL per gal is plenty.

500 ppm is pretty strong too.

7.2 pH is way too high. are you sure your meter is calibrated too?

do you have an air gap b/t the net pot and the res water level?
