Guide to Getting Rid of Root Rot

Looks like nute burn.
What are you feeding them in your solution? And how much?
5gal distilled water mixed with Dyna-grow (1 tsp per gal water), Rapid Start (1 tsp per 5gal water), and a pH balance of 6.7 in a bubble bucket. Treated it yesterday with drops of 3% h.peroxide. Today the base portion of the steam is getting skinner than the top half. : /

I just went through a case of some form of pythium which I'm pretty sure started in my cloner and hit all the phenos I had going, took a while for it to show up and the roots never had any signs (roots were white/clean/healthy looking). I tried some SM-90 which if anything made them worse, then switched to H2O2, gone.

Took about 2 months to save the last pheno but all of them are healthy/good to go again. While this may not apply or be as good for hydro systems, it worked like a charm in my 50% Pro-Mix/50% Triple Mix medium. The worst plant was an indica called Blue Pyramid that was so badly infected I was about to toss it, decided to try this and I'm about to flip it to 12/12 it recovered so well.

Cheap, effective, using it preventatively now through veg as it seems to help them/speed them up if anything:
35% food grade H2O2
Cut it down to 3% with filtered water
Add the 3% solution to my feedings @150 ppm
Bleach is cheaper and more effective. I only use h202 to clean, in between runs. Try it in your cloner 1mL/10L. I buy cheap dollar store bleach @ 4.25% so I bump it up to 2mL/10L...name brand bleach is usually 6-8%

For the cloner lots of people use bleach, I use it to clean my rooms and cloner as well. My post was targeted more for recovery of plants that are already affected or preventative, not just in the cloner but in soil or soilless. Not sure whether bleach would work in soil/soilless, it would probably burn them? It's pretty cheap too when you buy it at 35% and cut it to 3%. Have you used bleach in soil/soilless mix to recover infected plants or are you referring to hydro?

I tried H202 on my system, it didn't take out any of the bacteria gunk on the inside of the return lines. Neither did Clorox or clearex. I'm hoping that what I was lookin at was dead bacteria that was being recycled through the system. This is what was turnin my flushes a charcoal gray color until my pump couldn't pump any more. Maybe I need to use more H202, I thought a bottle of 3% grade would be enough to sterilize both buckets as well as other parts including the pump.

I can attest to H202 and SM-90. I put a little SM-90 in during res changes, and I add 1 teaspoon of H2O2 per gallon EVERY THREE DAYS. Water is always clear as a bell, roots are completely slime-free, just a little browned from the FloraNova nutes. Of course, I have only one grow under my belt, grow 2 is underway, so maybe this time will be different. I hope not. :)
Dude check out my roots if you can please

short version....clean bucket, add h202, 1tbs per gallon. make sure you have lots of bubbles, and keep your res temps down. light proofing is important too....Loola
Hey man, how long until root rot starts when temps are high? The reason I ask is I'm using a DWC and I've been doing good just rotating frozen water bottles daily and using h202 once a week. What I'm worried about is when I go out of town for 2-3 days. Any advice? Should I just invest in a chiller?

Thanks!

SM90 for DWC!

That's all I use and it always works ALWAYS!


The ultimate test of SM90 is when I ran a RDWC in one space I had for a backup system with no res change or cleaning for almost 2 months. Just SM90 and nutes and no chiller 74-76F res temps.

If that cannot convince someone at how good this stuff works then .. well have fun getting frustrated then.


SM90 is my backbone and even I will say it's partially why I am successful at hydroponics.

SM-90 is a surfactant? Is what you're using different? Link?
