One_bell here, newbie and need advice on RDWC and auto's for 2nd run

The roots are starting to look different:

The left looks darker then the right one, left:

What should I do now? Is the left one still savable if I get some hydroguard?
 
I do have voodoo juice from the AN starterkit (and the rest of it) laying around, should I add it? (Unfortunately Hydroguard is not available in my country)
 
Ufta, that does not look good :( So the darkness started near the netcups? How far do u keep the bottom of ur cups to the waterline? Also, u r using hydroton for the grow media? If so, do u fill the cups to the point of over spilling? I'd b willing to bet that is rootrot as u probably have already figured out. Hydroguard is supposed to b good at reversing it but I have no clue how far into rootrot it will help.

Unfortunately the reason I think my last grow went downhill at the end. At that time I switched over to the Terra Aqutica nutrients without voodoo juice and could not acces my plants buckets anymore because of the under canopy lighting and scrogg net... Now it all makes sense to me.

Ouch...yeah they look worse. I think there are methods for reversing the damage using peroxide but I've already showed my stupidity enough on this thread so hopefully one of the smart guys can help;smoke
I kept thinking those roots were progressively getting worse.
Is this a not enough myco thing? or should there be something else in there? @Stoneyluv @Observer ?? I had my great white container dug out and everything...now I'm scared lol

I don't think that's the case as he is using great white I believe. Maybe the extra stuff in the great white combined w his nute solution caused a bad reaction? I will show my stupidity though ;) I'd use that voodoo juice, those roots look terrible

maybe try that again first, if it continues getting worse, maybe reset that plants bucket, h2o2, and then add ur BB again AFTER the h2o2 has had time to break down, doesnt take long, minutes.

i use 34% h2o2, at 5ml per gallon.

you may want 3% at 5ml per gallon. start small and work up first.
kill the anerobic bacteria and tickle the roots with oxygen.


its throwing out new roots uptop trying to save its self.


that brown mass have a slimy appearance to it or feel?

i suspected it was a root system issue, plant isnt uptaking nutrients in an ideal environment for it.

something could of killed them, maybe he didnt use enough, maybe there was not much of a healthy colony on that plants root system to start with, not sure.

cant say its water temperature and O2 related just yet because he has a chiller right? and if its bubbling thats enough for o2.
 
I went a head and added 10ml of voodoo juice (Recommend 2ml per liter) to the buckets which exceeds my normal dose of vj by times 2. Also added a teaspoon of Great White to each of the three buckets to make sure the bennies are thriving and hopefully outnumber the bad stuff.

Also, I think (despite looking awful lol) preflower has begun?

Can you use H202 together with Great White or will it just kill off everything?

Yes the water is constantly between 17 and 19 degrees Celsius, with an average of 18C. Consider the watertemperature steady is save I guess. The temperature is monitored 24/7 by the bluelab Guardian WiFi and secondly measured by an Ampera pen. I also increased the air output by mulitply it by 3 with a bigger airpump and three times as much airstones as standard is fitted in there.

You spotted the beginning of the root rot earlier on, april the 29th. At that time I was still convinced I only needed Great White to prevent root rot. I need to pay more attention in the future...

more than likely, it will kill them, the free radical oxygen is just too strong/reactive on singular-cell organisms.


so that was my logic for saying use the VJ first maybe so we dont just kill any BB, but if its that rotted.....maybe the BB isnt working and pathogens have taken over anyways, so next move would be h2o2.

wish moe or aqua were around rn



  • Hydrogen Peroxide Breakdown: When hydrogen peroxide (H2O2) is introduced into water, especially in the presence of light or organic matter, it is unstable and breaks down. The primary breakdown products are water (H2O) and oxygen. This breakdown can occur in a couple of ways, leading to different oxygen species.

  • The "Free Radical" Action: One way H2O2 breaks down, particularly when it's acting as a disinfectant, involves the formation of highly reactive oxygen species, often referred to as free radicals (like the hydroxyl radical, OH⋅, or the superoxide radical O2⋅−). These are molecules with unpaired electrons, making them extremely unstable and eager to react with anything nearby to achieve stability. When these free radicals encounter the cell membranes, proteins, or DNA of microorganisms, they cause rapid and severe damage, effectively killing the microbes. This is the mechanism behind H2O2's antimicrobial properties.




  • The "Beneficial Oxygen" Action: The oxygen that benefits plant roots is molecular oxygen (O2). This is the stable form of oxygen we breathe, and it's essential for root respiration. Roots use O2 to convert sugars into energy needed for growth, nutrient uptake, and other vital processes.


  • How H2O2 Increases Molecular Oxygen: While the initial breakdown of H2O2 can produce damaging free radicals, these reactive species are short-lived. In the root zone, the breakdown of H2O2 eventually contributes to an increase in the overall level of dissolved molecular oxygen (O2) in the water. This can happen directly through the complete breakdown of H2O2 into H2O and O2 catalyzed by certain enzymes or reactions, or indirectly by preventing anaerobic conditions that deplete dissolved oxygen. Think of it as H2O2 being an unstable source that ultimately releases stable O2 into the water as it decomposes.

U only have 5l of water between the 2 sites in ur rdwc? Or was that 10ml per bucket? How big is ur system?
 
Should I add a new dose of vj again tomorrow? Or wait a bit longer? Or start with the H2O2 then?
if its just getting worse, id think.

but

since its R/DWC , id be concerned about the h2o2 going in to the other plant zone that is doing fine and fucking with its RTZ/Beneficial bacteria. (root zone)

@moe.red



otherwise, id isolate that plant if possible and run h2o2 in that zone/bucket.


and these are autos
 
I still don't understand how I got root rot in the first place with the water temp constantly at 18C and more then enough airation and Great White... Atleast I figured out what was wrong with my first attempt and the current problem. Time to act lol

I'm anxious to see the turn around.....just read up on voodoo juice and found this....

"Voodoo Juice is a product that features four hand-selected strains of bacilli134. These bacteria work together to optimize conditions for increasing the surface area of your root zone13. While it can promote root growth and beneficial bacteria, it cannot fix root rot2."

Your going to need to use peroxide to kill the rot first.
 
Thanks for the headsup, I will buy some peroxide ASAP. I am planning to do a reservoir change tomorrow, and will let both plants soak in a bucket with RO water and peroxide for about 15 minutes, rinse the roots with RO water before and afterwards and put them back in a clean system. Sounds like a plan?

You'll need to circulate it through the system also. Got this from AI.....
For treating root rot in a hydroponic cannabis grow using a deep water culture (DWC) system, hydrogen peroxide can be effective when used properly.


The general recommendation is to use 3% hydrogen peroxide (the standard concentration available at drugstores) at a rate of about 2-3 ml per gallon (or about 0.5-0.8 ml per liter) of nutrient solution.


If you're using a stronger concentration like 35% food-grade hydrogen peroxide, you would need to use much less - approximately 0.25-0.5 ml per gallon, as this is significantly more concentrated.
 
If it was mine I would just run it through the system and then do your change out with more peroxide till the roots clear up....after the rot is gone you can introduce life back.
Some run sterile the whole grow with the peroxide so it definitely won't hurt anything.
