  Root Rot what do I do??? I get asked this question a lot so I'll try and cover all the basics here.

  First figure out what is causing it, it's either a light leak or something organic has gotten into the water, this has to be fixed or it will just continue. 

  You will need 3% H2O2, either from the drug store or you can buy high strength 34% H2O2 and then dilute it, you'll need a dilution chart. If the plant is in early veg I'll use the drug store stuff, if it's later in flower I tend to use the commercial stuff. The reason being is that the drug store H2O2 has more preservatives in it that could possible (maybe) hang around in the plant, idk. Make sure the label says 3%, there are different strengths. 

  I use a pitcher that holds the net pot or I remove the lid and net together and place the net in a pitch that way. I do place an air stone in the pitch with the plant and I'll let it bubble for 30 mins. You can use the air stone from your system and that way you've sterilized the air stone to. So while it's bubbling for 30 mins, I'll dump the grow bucket and wash it with soap and water, don't forget the bottom of the lid, just wipe it off.

  After it has bubbles for 30mins I rinse the plant with clean RO water 3 times to remove any remaining H2O2 and return to a clean bucket and fresh nutz, I just pour it over and through the hydroton, rising away whatever needs to be rinsed away.  Now I use beneficial bacteria so I will add that to the grow bucket with the new nutz. Then the next day I'll add back the same beneficial bacteria cause if any H2O2 was left over it will kill the beneficial. 

This is root rot.

Bubble everything for 30mins, hydroton and all.

This is what I found and have used these amounts with success.

If you need to treat your whole system you can, just stay within the amounts given for the proper amount of H2O2.

  Here I got fed up with this one and chopped of her roots, and here she is 4-5 days later, can't hardly kill them. lol

  @stoned ape, If your unable to remove your plants from the system then drain and fill the system with H2O2, pour the treated water over and through the hydroton, rising it well. I would splash that shit around and make sure to get it on everything. I would over-fill my system if possible to engulf everything, then after 30mins or so you can drop it back down. 

  H2O2 will dissipate in 3-5 days, it will turn into 100% water. After that anything can move in and take over. So if your doing a whole system you can treat it one time or you can keep adding H2O2 and that is known as a Dead Grow. I use beneficial so that's known as a Live grow, and if you use bleach that's a Sterile Grow. I didn't name them so don't blame me. lol

  My biggest problem area was always light getting in through the hydroton, so I cover that shit and it's cheap insurance, double check for light leaks. Then make sure your not using anything that has organic material in it, even if it's on your manufactures feed chart, double check. 🖐️

Nice one @Woodi2 so her is a picture of the settup:

857ECFDD 6D20 42B2 AE1A 20B62257FBB7

1 question, do i run a full res for 30 min with only the hydrogen peroxide and no nuts? They are at day 19 of flower if that is at all relevant?

2 question, ther is no hydroton, only the smal root riot cube they got started in, do i still need to rince it from the topp? Or will floodibg the pipe and so also the cube do the trick? (It wil be a pain in the ass to rince it all from the top)

I think i got the light leaks coverd, they all got a black neopren ring to cover the pots and i taped a mylar patch over the pots to try to make shure of it, but it is hard to control that it actualy woorked. i suspect a water build up in the pipes causing nuts to stay stagnant/still at the Botom of the pipe is the cause, idk what Else it can be, the res is cooled to 18c and pumped full of oxygen from the air Stone and i dident ad annything Organic over the last 18 days, so i wil slope the pipes some more towards the drainage pipe and hopfully that wil fix it if it was the problem to start with. 
i did use some super thrive in the veg stage to help them establish, but stoped it at the start of flower ( that shitt is pricy!) should i add some back in after? Or maby some cana rizotonic to help the roots recover? Or mabe just go for the h2o2 aded steril option? Thos are the 3 options on shelfe atm, what whold you recomede? And @woodi2, thanks man!

You grow better!

You can simply add it at the proper amount to your existing rez, no drain. You can let it run for 30mins, 1 day or 2. It should get to everything it needs to. Just let the system run, then you can drain and change or you can keep adding H2O2 till harvest. If your going to do that then you may want to get the 34% and look up Dilution Charts for Hydrogen Peroxide and search till you fine 34% to 3% dilution chart. Once you have created the 3% that is what you'll use daily, DO NOT ever put straight 34% in your system and ALWAYS wear gloves and eye protection with this shit, it will burn the holy fuck out of you, you'll see.

@stoned-ape, Bingo!! Right on, so now after dilution use that to whatever strength you need according to the chart. I double checked, and this is what I found. You are correct Sir!!

1 part 12% H2O2 to 3 part water (12/4) = 3% Hydrogen Peroxide
