Best thing to do is start again and learn the lesson. Dwc/rdwc is a system that has no give/play. You have to keep it with in its parameters at all times. The idea is that your plants are getting beyond optimum condition to grow in 24/7. This is not the case with yours. You will spend the next 3months adding this that and the other but nothing will work. Its not about curing illness in dwc. Prevention is key. Take large cuttings from your vegged plants is best you can do. And clean out system start again. Good luck you will get there

Take clones now, those plants are fuct. But if you want to give it a shot rinse off as much crap before you start dunking in peroxide and like already said you will need mutiple dunkings and I would even pour some down through the net pot.

Also, if you can get 30% peroxide, use that and dillute to 5%

they look pretty rough.

i think peroxide would be what i would try. and alot of dead roots and gunk is gonna come off. you will need multiple soaks, refill with more peroxide, rinse and repeat.

what % peroxide can you get quickly?

I can get 35%. I'll do that rinse in the next day or two. They are soaking in Physan again right now.

Right on.



It also sounds like no one here has dealt with the Wettable Sulphur headache I'm dealing with. Geeze, what a mess lol. Lesson learned. DO NOT USE WETTABLE/SPRAYABLE SULPHUR IN DWC. YOU HAVE BEEN WARNED.

i'd skip the physan
www.physan.com

Hydroponics

Physan 20 Greenhouse Disinfectant can be used in a variety of hydroponic applications to: 1. Prevent the development of disease 2. Kill algae that may form on system surfaces and substrates...
www.physan.com www.physan.com

says it does more to kill algae. i didn't read the word pythium in that whole page.

it does say this:
However, it should be considered that tender root systems are potentially at risk from a continual bath of Physan 20 solution.

People recommended Physan 20 for the rot specifically. I let the roots soak in the physan/pure water for 3-4 hours. Brown Algae is root rot/pythium? At least, that is my understanding of it.

I will do another wash with H202 tomorrow.

I used 1 ml/gallon of 29% twice a week as a preventive, seamed to work.
Wouldnt even bother if your at 8 weeks,Next round youll know better.

Yup. 35%. For some reason the cap would have some on it when I unscrewed it. And I always forgot.

Glad I stopped using it.
