Root Rot? Please HELP

[Row]

Hey all

This is my first proper attempt at hydro and i think i may have some root rot.

Im fairly sure it is root rot, but i was hoping some one would be able to give me some advice about what action to take.

I have read the sick plant guide and will get and add some sm90.

Also i think the cause is to high res temps as iv been waiting for a larger res to turn up so the water isnt heated by the room as fast.

Currently the res is 75-80 and should be 68

I am not sure if it is to late for the plant or if i should cut the rot looking bit of root out, or if using sm90 will be enough to fix the problem and of course i am puting a larger res in which should solve the temp problems.

The roots dont seem that slimy and also the roots either side of the light brown looking bit are white including the new root growth, so is this a good sine?

Here is a pic

Almost all the other plants look like this

So am i fucked?

is removing that plant the way to go?

Is cuting the rot looking bit out enough?

Will lowering the temps and using sm90 cure it?

Again will is fuck the rest of the plants?, man im so worried......

is it early enough to be fixed and not a huge problem, as the roots have some white either side of the rot.

Any and all advice is much appriciated.

Thanks

If it's disease like pythium then yes it can spread to everything exposed to the same reservoir.
If you don't already have any hydrogen peroxide, you can get some from an all night store if you're into treating this like an emergency instead of waiting for the sm-90. I gather from your questions that it's just one plant so far, I'd take it out of the tub and try to treat it using h202 in a separate container, like bubbling it in a bowl for a while. You can cut away the gushy feeling portion and then soak it or swish it around a bowl of h202 and water about an 1.5 ounce of drug store strength 3% h202 per gallon of water for the sick one, and one ounce per gallon for the tub.

Treat the tub with h202 also with the hope it catches the infection before it spreads to the others.

But also, I would go ahead and get the sm-90 as it's said to be the shiz for root disease in hydro and treat accordingly as a follow up preventative measure for the entire reservoir and all of it's stations.

Here's a helpful growfaq on the old school h202 root rot methods

hth & good luck

Hey 10k

Thanks for the quick reply

I have some h202,

I also just got the large res, filled it made a fert mix and have it running.

I also just cut off a large portion of that plants root mass.

Should i just add 1mil per gallon of h202 to my res now? and add it again every day in the hope the infection rot goes completely?

also i have Grozyme in the res as i heard that helps with replacing the enzymes lost by the h202 killing the good bactiria.

And yes it does seem like its just that one plant at the moment and the rest have nice white roots like the picture above.

Thanks

Thanks for the link 10k, i just read the whole lot,

Seems im on the right path to at least helping get a grip on it, i didnt like the whole, its impossible to get rid of it 100% though.

But lets just say i can from now on, keep res temps at 68-72 max,

Use h202 daily at 1mil per gallon?

Change res often, cleaning with h202,

Use sm90

Use flora sheild

Use Grozym

Keep plants healthy

Will i beat it, and have good growth/yield etc? or am i just genna be failing from now till i harvest, i say this as there only veging at the moment and id rather cut my loss's now.

Also would it be just safer to remove that plant all together?, losing 1 plant to save the other 39 is well worth it, by the time they finish the gap will probably be filled by the plants around it anyway.

Thanks

I've seen alot of threads where people have been able to combat root disease when they catch it in early stages like you have. I think you'll be alright if you take the measures you've outlined. However, you'll not need the grozym or florashield if you run the sm-90 as it'll pretty much sterilize everything.
You're running a GH flora lucas mix if I remember right, and it should be ok since its a chem hydro and not an organic type grow so "sterile isn't a dirty word" heh haaaa yea I said that

That being said, I agree you'd be better off to ditch that one plant since they're all small and the others will fill in the gap when they all start fighting for canopy space.

Glad to hear you guys got this under control. I've read a lot of 10k's posts and they are very intelligent. The only thing you may want to add is an air pump/stone. This can help a little by giving more O2. Best of luck.

Checked is morning and the res never seems to go above 72 now that i have a 100gal for the table, so thats 1 thing checked off the list.

Alwayslearning, i have 1 eco air 4, with 4 8" stones and a separate blue air pump with a 12" stone, the res churns nicely.


Im still unsure about H202 though, i have read so many contradictory things about it, some saying that it is good and others saying it isnt, i have mainly focused on soil though and have come to the conclusion it is not good to use in soil, even though i use chem ferts but i do use good bacteria(subculture), which i think has definitely improved my root mass/growth and possibly yield.

Check this article on h202, very very interesting, also this is the way i see h202 and hence why im skeptical to use it.

http://www.maximumyield.com/ask_erik_article_sh.php?articleID=386&yearVar=2008&issueVar=November

In the sick plant guide it talks about the h202 working in the short term but by killing all bacteria, good and bad, you leave your plants defenseless to bad bacteria.

Does this include pure chem hydro? or are there NO good bacteria? i have been useing Grozyme and was going to add some subculture.

Also does the sm90 kill bacteria like the h202?,

[Row]

I added sm90 to the res today, as i understand it the sm90 will coat the roots so then no bacteria good or bad can attach to the roots and live there. Therefore even if you think of h202 like the above article does, it may be worth using it to kill the bacteria that is around as good or bad it cant live or do any good/bad while im using sm90.

Any one have any more advice about whether h202 is worth using/good to use with sm90 or not?

[Row]

I really cant decide whether to add h202 to the res with the sm90?

Please someone enlighten me

use h202 w/ no dumping of run-off and wicks. h202 keeps sludge at bay.

Row, you appear to be using green garden hose and jubilee clips in the Hydro solution ? Did it come as a kit with them in it new ?

Both not good and will intefere with the plants in a bad way, use just growshop hard black plastic fittings and no metal [apart from proper stainless] ... ever.

Insulating your B/W plastic top plate will help reduce temps, especially in the vulnerable rootzone, and the first few weeks, polystyrene works well, slats of Kingspan better, and a bigger res as well like you say. Like a lot of growroom problems, there is often no Silver Bullet, all you can do is look at the whole process and try to make little improvements here and there.

Good luck with this, it seems to be plaguing the UK right now, some might be passing around in the clones so take care.
