HELP! 3% PEROXIDE IN HYDRO!

Hello everygrower, I'm currently having a big problem in my rdwc system, and really need an advice.

The seedlings have been in the same res for one week with 12% Food Grade H202, no problems at all.
The fact is that I've ordered some more h202 time ago but they are still not shipping to me, and I've already used the last drops i had..
Now temps are rising and I'm starting to see some SLIME on the roots.
:cuss:
I'm thinking about a solution, given the fact that i can't get more food grade peroxide right now..

Do you think that I can run the system with some normal "dollar store" Peroxide for a couple days?

Would the substances in there cause any harm to the plants?

How much 3% Peroxide should I add for gallon or liter of water to get the sterilization?

Looking forward for answers, and a big THANK YOU.
:roll:

Why are you running h2o2 continuously?
Temps too hot?
Personally I would change the reservoir and add a little pool shock till I fixed the cause

I'm running h202 for the first weeks to give time to the roots for developing (to make sure everything is clean and sterile) , then I plan on using bennies when they'll have a place to build a colony..
Temps were good (65-72) till yesterday, I left the house and came back to 78 F, and the problems are showing right now.

I've never tried pool shock before, don't know if it would work better than 3% h202..
Never tried house Bleach as well.

It’s ok I never tried running h2o2 continuously
Let alone running without nutrients
Is this something you have done regularly?

Thanks for answering.
I've been running dwc and rdwc only in my last few runs, let's say since one year ago, and with the right temps, I've only had problems when running bennies from the start.

That's why I figured out this way of setting up things, I won't use h202 for the whole run.
Mainly for price, and to avoid interactions with chelated nutes..

Sterilization only for the start and to fix problems, while bennies go a long way

Ok two issues I have encountered in dealing with contamination have been
Water temps I found my temps rose because of the heat from my pump
Although it pumped fine the little bugger was heating my res 6-8 degrees and was only two years old
New pump solved that
The other is not having cleaned everything properly before starting next run including the cuts
That is where the pool shock comes in
I would run it for a day or two then change water and good to go
All this may not apply to your situation but it might help you find why you have root rot so early

Pretty sure it's from the heat rise experienced in the last two days, now I've fixed the temps.

I think I'm going to try the drug store peroxide first without changing the res right now (water looks clean, I've got multiple inline filters).

If the problem is persisting I'll try running
plain Ro water with pool shock for a couple days while foliar feeding.

I've read that are three different types of chemicals in different pool shock types, I think I'll create another thread to ask about these ones and the right way to use it..

Also I've not found coherent info yet about the right dosage of 3% h202, so i've simply done the math and will maintain the proportion I've used until now with 12% (1 ml/L).
That would be 4 ml/L or 16 ml/Gal of water for the diluted one.. (If I'm not doing it wrong as I'm stoned AF right now:bigjoint:)

Peroxide doesn’t really clean your equipment
It eats the dying roots
Pool shock cleans the system
I use this one at about two granules per gallon

Peroxide is not as effective as chlorine based sterilizing agents as other suggested. I've use regular bleach in hydro for decades. They're all chlorine based and do the same thing, I just find it easier to use bleach than Pool Shock.

If you really want to use "bennies" I would look for Southern AG garden friendly fungicide. I think the dosage is 1ml per 10 gallon if I remember that correctly. Stay away from "Great white" and other inoculants intended for soil and containers.

Ive used oxy plus all the way through huge tanks moving to plants with huge root systems. Kept the tanks an any pipe work an roots sterile while active an stopped any mineral build up in fittings an corners. It dont stay active very long. So I used to add it to my tanks once or twice a week. With the pumps running 3-4 times a day it would completely cycle around the whole system multiple times till inactive. Then not long after my next dose addition would do the same, I never ever experienced any root issues or blockages while using oxy plus/h2o2.

That's interesting. Do you use bleach with plain water or regularly dose it into the res? At which dosage..? Still find myself a bit scared to give my babies an house cleaning product but 10 years are a lot of experience :mrgreen:

I use GW with an extremely low dosage, kinda slowly inoculating it and constantly filtering the water..
In my country is the only option that i have unfortunately, but honestly I've never experienced any problem using it this way, at all.
Even with water temps around 75, water has always been very clean and really no staining in a RDWC system, no algae, no slime and really thick and fast growing roots.
The only thing is getting the bennies to take over then system before any other harmful shit makes a colony on the roots

Here the dilution calculator. Check percentage at the back of the bottle. I just add 3ppm to everything going in to the res and every 4th day if I'm running bigger water volumes without regular top offs. 3-5 ppm is recommended for DWC, Good luck! Chlorine dilution calculator

Based on this post I used 12-15 ml/gallon or 4 lm/litre of the 3% h202.

Nutes lockout / root rot ?

Hello everyone, I'll go with the rules first and then explain carefully my situation: 1) Pic in attachements 2) Growing indoor or outdoors: Indoor 3) Watering schedule: Water as soon as the soil gets dry 4) Growing Medium: Atami light mix 5) What stage of growth: 4-5 weeks into flowering...

I used just plain Clorox bleach for years. Never had any issues with root rot except for when I first started doing hydro and used H2o2. Bleach is much better. And to those afraid of bleach, it won't harm your plants unless you use too much just like anything else.

After less than 12 hours with 0,1 ml/L bleach, roots on the seedlings are looking white again and the bit of slime had nearly completely disappeared. (Maybe they look a bit skinny, wrinkled and twisted compared to when i use bennies, but still healty) Crazy how fast it worked. :weed:
