Root rot - help me save my plants!

[Mindovermatter]

Ok seems everyone has lost interest in my other thread "help! please". Anyway I think we came to the conclusion I had root rot. So now I wanna know how to fix it. I really dont want to lose these as they are my last bogglegum seeds and you know they cant be found anymore. So if you can come to think of anything, anything at all please inform me. They are too small to take clones from. My res temp is about 70 so no temp problems, its just that before I put them into the bubbler where they are now, I had them in small plastic pots and handwatered them appearently way too much. Now, I cut about 50% of the pots open and have them in a bubbler slightly above the water level. The medium is rockwool on top, coco on bottom, in small pots above the water level of the bubbler. Some of the roots are yellow/brown but not slimy or anything yet anyway. I think its in the early stages.

Ok so been reading...
some say hygrozyme..some say no....
some say h202..some say no...
some say enzymes..some say no...


Ok I live in europe so I cant get any hygrozyme...I have some Hesi Powerzyme...and can get some H202.

Tell me what to do PLEASE!

i have been told that hygrozyme is the only enzyme product that you can use in conjunction with h202. i have used both of these to battle it but it was a little more proactive than reactive.

do you use buckets, bins, trays? you can try appling aluminum tape and panda plastic over each, for a cheap fix. you can also freeze 20 oz bottles full of water, and put them in your rezzes/buckets. they do help, but only by a few degrees. still at this point every step you can take to stop it is a good one..

how long have you noticed root rot symptoms? 1/6 of my girls had an issue with it 1-2 weeks ago and i removed a lot of the rootmass because it was dead, black, slimy.. it slowed down in growth but showed no sign of sickness, and is now bursting out with new roots as the temps are fixed.. so its possible to fix if you havent had it too long..

good luck

lorax,
I have no temp problems. If I apply aluminum wont they be worse? I have to dry them they are very wet.
Noticed root symptoms about 2 weeks. none of the roots are black & slimy, they are yellowish/brown..

wait, you are in dwc and your problem is caused because your rockwool is staying too wet? sounds like your water level is too high, no? you say the netcup is slightly above, it should be a solid inch, especially given the fact that you are using RW which retains moisture much more (not better though, imo, as retains too much perhaps)

I dont think rockwool is a good medium for dwc beyond cutting/germination because it retains moisture too well..Ive always used hydroton. due to the nature of dwc the roots sit in the rez and they dont need the extra help, they need plentyo f oxegyn.. not sure what to tell you, after re-reading (sorry, blazed off some sativa) it is clear that you have identified the cause of the problem in the rockwool. obviously because temps arent a problem, completely ignore my first post, except the first part about h202/hygrozyme.

don't know what else to say besides lower the water level a little if its less than an inch away.. however if its just "some" are yellow/brown that sounds like its not out of control. if theyre under HPS or MH and in a bubbler now, with proper water levels it should start to dry out a little.. problem is its RW.. try hydroton next time, you may like it better.. good luck

Does it smell like rot???

 

[Mindovermatter]

When i lift the lid and put my nose in the dwc...yeah theres some funky smell alright

 

[-VT-]

Anyways ............ the lorax is right...

you overwatered them....and oversaturated the medium/substrate....

let things dry out and they will recover with optimal root zone temps(as the lorax said...lower the water level)

If H202 is all you have access to then use it....it has a short half life...so you have to add it regularly....I never use it and can't remember the intervals/dosage I apllied when I did (used the OG FAQ)

If you ever do get root rot....trim away the rotted shit and slime....rinse em and soak 'em in h202...change the rez and SCRUB like a mofo.....change the airstones and the lines from the pump....sterlize the system....

p.s. Some pythium have a wider host range than others....in other words...some can come pathogenic in cooler temps than others.....

good luck

 

[Mindovermatter]

someone suggested myrcozial bacteria...I can get this stuff called "mineral magic".
link to mineral magic

I'm not sure what the active ingredients are in that organic product....sounds like a "beneficial bacteria" product....

Just to make sure you know the difference....in how these things work....

ENZYMES: they breakdown salts and plant waste/matter and make them useful to the plant(s)....

Beneficial bacteria - they kill pathogens and proliferate in the reservoir over time...this is most effective when there are NOT frequent rez changes IMO

h202 releases oxygen that kills shit....like bacteria (including any beneficial bacteria)

My experimentation (multiple loss crops) has led me to the conclusion that the most effective method for root rot prevention is cool root zone temps and lots of bubbles....

Once an attack is fully underway...and it gets up the root collar.....none of these products will stop it...these products are preventitive measures...not a root rot panacea

-VT-

 

[Mindovermatter]

ok VT I understand but I got to make a try...im off to get some h202..see ya in a few

 

[-VT-]

the h202 will definitely kill pathogens

good luck

 

[Mindovermatter]

Ok I bought some 17% h202 and some chlorine. This is what I am doing now:

I killed the plant that seemed to have the largest portion of yellow roots. I am opened it up completely and inside I saw NO yellow or brown roots.

I put the 4 remaining on a table with a fan blowing on them to help dry them out quick.

I put 7 oz of chlorine and 3 oz of h202 together with about 2 gallons of boiled water+the airstone+airstone tubes in the tank to disinfect.

Any ideas are appreciated.

I wanted everyone to see the problem. I put an arrow on what appears to be root rot on Mind's plant. Click on it to enlarge.


Hydrogen peroxide rates I have are for hydro 1 teaspoon (5ml) 3% h2o2 per gallon of water (3.8L) daily or 2 teaspoons (10ml) only 2-3 times per week. 70's Pothead applies 1.4 teaspoons (7ml) at rez change and 1/4 rate daily. In soil, he uses 2 teaspoons (10ml) per gallon (3.8L). He said these rates he uses came from overgrow and he has not had root rot. If your using 17% hydrogen peroxide reduce these rates. For cleaning tanks and rez's, 3.67 ounces (110ml) per gallon (3.8L) of water.

Your roots appear pretty much normal except that small area that is suspect. Don't abandon any plants yet! They don't appear to want to go deeper into the media like I already pointed out. They are clustered at the top of the media. This could be lack of oxygen.

 

[Mindovermatter]

Thanks Sproutco =)

Yes, as far Ive read I am supposed to use about 4ml of this stuff for every 10L, but thats for maintaining right? After the tank has been disinfected I am going to put a solution of water+enzymes+h202 to the stem and let it sit there for some time.

Problem is I dont know how strong the solution should be and for how long they should sit in it?

Is that for the 3% content?
I don't think it matters so much tho..since its only cleaning...or?

 

[sproutco]

Yea its for the 3% content stuff. It does not matter much with cleaning but for using it on your plants do the math.

Here is a handy webpage with all the h2o2 rates including using 17%. All the math is figured for you: http://www.angelfire.com/cantina/fourtwenty/articles/h2o2.htm (you might have to allow pop up's for the page to load)

 

[Mindovermatter]

Hmm ok pythuim is a fungus...h202 is a bacteria killer...looks like it wont have much effect..am I screwed? I will upload a pic of the killed plants root later.

Sproutco: the math is no problem, I was the school champion in junior high =)

Sorry I wanted you to see this and I edited my last post.

Oxygen that is electrically charged funny like in h2o2 will kill anything.

 

[Mindovermatter]

What I wanted to know was the quickfix concentration when I let them sit in it for a couple of minutes. But I guess you mean its the same as maintainence?
This is what OG FAQ says, but it dosent say how strong:

Emergency Treatment:
1. Hydrogen Peroxide root dunk
-Remove each plant from system, snip off diseased roots.
-Dip/swish each plant and container into a strong H2O2 solution, until diseased roots have been removed. Repeat as required.

 

[sproutco]

I still don't know how the plants are being grown. You said they are in a bubbler. So, the roots are supported by the rockwool and coco. But the whole thing is submerged? Both rockwool and coco?

That sort of reminds me of taking my now ex girlfriends son to the swimming pool. He was probably 2 years old. Well, he was wearing a diaper but it was not intended to be used in water. Pieces of the diaper began in time to fill the pool. Horrible thought. I got out quickly. Lol.
