I used this stuff, its hydrogen peroxide based but it lasts in the res for up to 5 weeks whereas the straight peroxide I think you need to add to the res every couple of days as it's not stable.

What he said.. . Instructions are on bottle...

Feel the roots.... are they slimy and soft or not slimy and firm?

If they are firm you'll be ok... with dwc you need to either have a completely life free water by using h2o3 or you need beneficial microbes to protect the roots. Beneficial can give you ph issues so I fo completely clean

Hey guys a bit of an update:

I had a thorough look and think about root rot and am not convinced that my plant has it for the following reasons:

The roots don't feel soft and slimy - they are not slimy and firm, even the roots with the brown on them
The plant never drooped before the leaves went dry and brown - this seems to be a symptom of root rot
The brown stuff is only on roots which are not submerged in water
The brown stuff has not spread
I saw the same brown stuff coming out of the dripper when I removed the bubbler - I'm pretty sure its just sludge from the nutrients (the additives are very concentrated and very dark brown in colour)

I think that what happened was that the plant wasn't getting enough nutrients after I prematurely removed the bubbler. I removed it as soon as I saw the first roots hitting the water in the res. I suspect that as a result the plant had a sudden shock where most of the roots it developed (the ones in the clay pellets) were no longer getting any water and so the plant wasn't getting enough nutrients... I've reinstalled the bubbler and can already see fresh white root tips begining to emerge from the pot and the dryness in the leaves seems to not be increasing.

Still, I've added H2O2 to my res, double checked for light leaks and dropped the res temperature to 19 celcius. I've also removed the dead/dry leaves.

Ill keep a close eye on the roots and see if the brown stuff spreads etc. and if the plant isn't recovering I'll reassess. Ill try and keep this thread updated in case anyone else has a similar problem in the future.


Please let me know if you think I'm very wrong lol

Thanks for all the help!

What do you mean by bubbler, the airstones?

I mean the small water pump which was dripping water from the res to the top of the pot. I'm pretty sure the drooping from those pictures is from topping the plant the day before (probably shouldnt have done this). The plant is no longer drooping at all and the new growth post topping looks healthy.

OK man, IMO the bubbler serves no purpose if the roots are in the water now, all it is doing is creating more heat and pushing water temps up, are you sure the improvement is not just down to adding the peroxide?

Damn your roots look super healthy lol

Yeh i agree with you on the bubbler serving no purpose once the roots have hit the water. My issues is that I think I removed it too soon once only 1 or 2 of the roots had hit the water (which is quite far from the bottom of the pot) so all the roots in the water are now coming from about couple of strands.

There even seems to be some new strands headed to the water.

Here are some pics:

Yeah you should start seeing new healthy roots come through now your using the peroxide, the issue is that for me the peroxide is not a long term solution unless you are happy to keep topping off the res with it every couple of days, also it will be killing anything beneficial, I personally use hydroguard for beneficial bacteria and the nutes I use leaves my water crystal clear, I used to use stuff which made the res brown etc but for me anything organic doesnt belong in DWC, synthetic all the way!

I didnt ask, how much solution does your res hold and how big is the pump your using? I give my girls 20l/pm of air and my res only holds about 16l of solution leaving a slight gap between water and bottom of net pot

Its a 54L tub with 20L of water in it for veg and 25L for flower. I'm using 2 air pumps one which make 5L/m combined. Do you think this is not enough?

There is quite a large gap between the water and the bottom of the net pot. About 4cm .

You definitely need the water to be agitated pretty good, I think you should just about be ok as you want a minimum of 1l/m per gallon, just watch out for your airstones getting gunked up and blocked with the stuff your using because if it's not root rot and is the nutes then your airstones are probably pretty manky??

Using a new air stone for one pump so I should be good for a while I hope. The eheim pump actually uses these round balls with cotton in them to produce bubbles and you can just wash the cotton.

What kind of air pump have you got? looks like theres plenty of bubbles in your res! Also, any tips for sourcing hydrogaurd in AU?

Thanks for your help mate, very much appreciated.

Hhhhmmm not sure to be honest, might be banned in Aus like it is in Canada, I could only find 1 or 2 places which have it in the UK, which countries can you receive goods from without tax?

Oh my pump is expensive, it's a hiblow hp40 but its lasted 4 years without issues and is quiet for an airpump

I think people on this site run this stuff instead of hydroguard but I've never used it so I cant say if it's good or not, there is a whole thread on it though and it sounds like some people have had success with it and others prefer hydroguard as made for cannabis so up to you I guess, you could give the dutch master stuff a try after you have used the peroxide for a bit or you could go the sterile route full time and get the silver bullet roots stuff

Here is the thread, I would read it and then make up your mind, also I think its strong stuff so read this also to find dilution rates

Fixing root rot: Hydroguard v Southern Ag Garden Friendly Fungicide

I am addressing root problems in my first ever hydro grow and seek counsel from those more experienced please. These two products are similarly priced, have the identical active ingredient, but at very different strengths according to their labels. So different that I question if one of them has...

I would personally get a bigger pump but I'm sure others may disagree!

Do you know if its OK to leave the plant in the setup while I flush/rush some plain water and H2O2 through the system? I assume the H2O2 will do some damage to the plant but if it is root rot then I want to disinfect the roots of the plant too yes?

Also, do you use air stones or aeration tube to diffuse the air into the water?

Yes mate, i would take out the plant then go wash all the equipment with a peroxide solution then once all the equipment is washed you can fill your res with clean water and nutes and also peroxide but I dont know what the dilution rates should be as only ever used that silver bullet stuff.

I run 2 6 inch flat round airstones in each bucket
