H2O2 amounts?

I'm struggling with a nasty root rot problem and have been adding bleach almost daily and it's not really solving things sooo. I just bought a 5 gallon pail of 35% peroxide and may as well try it. I do have a formula I got somewhere that is 10 X res size (100L) / 35 (strength) = 28.5 ml. Is this ok and should I add it every day? And yes trying to sort out temp issues as we speak. Thanks for any suggestions. Oh ya and my bennies didn't seem to help this run .

I mix 5 ml per gallon.
And then add another 3 ml per gallon every 3 days.

When I was battling a root rot issue I flushed for 3 days with just plane RO water and H2o2. I added 5 more ml's per gallon each day.

This is what I do. But the directions should be on the bottle.

The bottle is a 5 gallon pail of 35% so nope, no instructions lol.

Yeah no... You don't want to dilut it down to 3%.
Just use it as is 35% but I would pour it off into a smaller jug so it's easy to work with.

Make sure that you use gloves and eye protection. No joke.

For everyday use.
Add 3-5 ml of H2o2 per gallon of Nutriants solution.
And then add 3ml per gallon every 2-3 days.

Lol,, I was meaning to brake the five gallons down by pouring into five seperate gallon jugs,, and yeah just measuring 3-5ml liters to a gallon of water is good for small applications ,, 3-5%

I just use a syringe and suck it out of the jug. I just got it off kijiji for $100. It's getting impossible to buy it here. Water filter companies sell it for like $300 but they ask lots of questions re filter type, told them it's for my injection system lol. So basically that formula is pretty close to what you guys are doing. I have been adding 23 ml per 100L every 24 hours but roots are still fucked.

Root guard by Botanicare, is a root inoculate,, it my help, , it not to pricey

here a pick of to much crap put on roots for root rot made it to flower after started a tea but end product tasted like shit...

I put 2ml per 10L of 35%, my rez is 50L and I just followed the instructions on the label. Seems to work well.

I just ordered a gallon of Hydroguard from Amazon to try on the next tray so we'll see how that works but honestly I have never had this before and it's a bitch to get rid of. I would pull the ones but two are still alive and I can't give up on them .

Lol I said Rootguard,, I need to quit smoking so much before bed,,lol,, I meant Hydroguard but I'm sure you got that,,,, you'll save'm ,,

Well that's good I thought, "shit I ordered a gallon of crap" lol it's gonna take a bit to get here due to shipping but hopefully I can get a couple out of this run and clone em, they we're pricey seeds I took a gamble on. I am starting another tray on Saturday of Mataro Blue and white domina which I have done before. Going with a flooded root zone on this one I think. Just bought 100 mist heads on eBay lol. The passive chiller I just finished is in need of re-engineering, it seems to be warming the water lol, my outdoor coil needs about 100' more tubing I think.

I dont use the shit anymore, but a well known grower here suggests

1.7ml/L 35%

I have always used microblift pl but will give this a try on the new run, pretty sure I'll use the peroxide on this one till the end.
