DWC root rot? plz help

[blank85]

Ok so i transplanted clones into pots with rockwool then placed into a black tub. The mother plant had some slight root rot and i believe it was transferred to the clones.

Air is pumped in and the water temps are 15 - 20 degrees celcius. Low humidity.

I started to get pythium wilt and noticed the white mold growing on the stem. When i got a ec/ph reader i saw it was ph8 and 150ppm (tap water). I replaced the water with ph 6.5 water, 120ppm but 2 days later it was at ph 8 once more. Then i put rain water in which was ph6.0,40ppm and once more the ph went to 8 within a day.

I also noticed some green stuff growing on the bottom of the tub with bubbles all around it.

I have been treating the water with 3% h2o2. It helps for about a day or two but the plants are all stunted, roots arnt growing and some of them are pale brown. I get them white again with h2o2 but it never lasts.

The the first cm of roots just dries up and the plants wilt over and die, ive watched 6 plants go this way and another 4 look bad.

Now my idea is the stuff growing in the tubs is changing the ph, unless its the h2o2 but as far as i know h2o2 wont change the ph?

The ph 8+ stresses the plant and the pythium rages harder.

Could i take all the clones out, soak them in a a gallon of water with 5ml h2o2, disinfect the pots with h2o2 and then repot the clones into coco? Would this solve my problem?

Then i could let them grow in the coco while i disinfect the tubs and get proper water. Then when the roots have grown through and are out the bottom i can put them back into the tubs.

I cant beat the phythium with h2o2 and live in a country where i cant get hydrazyme or anything like that.

Any suggestions??

Thank you

Once you got rot the clones will have it as well. throw the plant away and start again. Just make sure it's rot first.

Id rather attempt to save them in coco first....

Its worth a try i cant just throw them all away.

Ive read on forums that you can save a plant with root rot by transplanting it into coco or soil...

Anyone on here been successful with this???

You have a systemic problem, with your environment. You can not get rrot on a dang clone without roots yet, duh, so you are getting it in your environment, air, water, or medium. Clean everying with bleach water and try again.

Here, I use simple tap water with the chlorine still in it to prevent rrot, or get rid of it on young plants if it does get started. I just dip the plant in a bucket of fresh water three times, then gently massage the roots with clean hands, then put it into a clean system. I have eliminated the problem this way.

You can save a plant sometimes, but they never yield as good. Your choice though. But take it from somebody with experience, it's not worth it.

In someways a waste of time, in others, an opportunity to learn, and hone ones growing skills.

I've grown more shitty diseased crops than I care to count. Slowly, but surely, I AM learning!

A positive attitude helps.

That's why i add straight tap water back to my RDWC (chlorine and all folks, no bubbling the chlorine out for me)

I hope you are learning that in early veg it's better to start over and not waste money, time, resources on plants with rot. The guy is a few weeks in veg, I doubt any experienced grower would do anything other than throw them out.

Somebody has put it in his mind that 1) You can beat root rot, and 2) it's worth it.

I would actually use 4 drops of bleach each gallon in the rez. Change out every 3 days. H202 does help but dissipates too fast.
But the guys here are correct in telling you something isn't right whether it being nutes, environment etc..etc BTW what kind of nutes are you feeding?

You can beat root rot, and it is not really hard at all.....

That said, if the OP's plants are still little 4" clones then it might not be worth it.

BTW if your pH is raising, then it's not pythium. And if the ppms are only at 150 or so, pH is really irrelevant. in fact, with no nutes in your water, pH really doesn't make any difference at all (so long as it is not straight acid or something ridiculous). If you are growing green shit you need to look into better lightproofing.

One more thing, if your plants are really small, i highly recommend raising the water level closer to the bottom of the rockwool. You said the roots are drying out in the gap....that means that your water level is too low (or that you don't have enough air to create sufficient mist). Try raising your water level up until the roots are more developed and larger. Also, don't forget, those plants aren't going to grow without nutrients, so the longer you starve them in pure tap, the weaker they are going to become. I would forget the h2o2 on small plants. I have had bad experience with using it on less than mature plants. Clean system, raise water level, lightproof.

And get nutes in soon

i dont see how root rot can tranfer from a mom to a unrooted cut if theres no roots cant have root rot id check u bucket and make sure its not got a light leak could also be algae does it smell? i ve been battlin rot for a min and finally won first thing i did was remove rotten root ifu pull lightly they should just come right out of the healthy ones 2nd rinse remaing roots good i grow dwc as well and i eliminated most of the organics i was feeding mostly the zymes they breakdown the dead roots and feed the pythium and i keep my res temps down with frozen water bottles added another airline for even more bubbles and insulated my buckets after seein haps buckets in another thread thanks for the idea bro i found a plumbers reflective foil tape used for insulating pipes which works great its 1/4in thick so i used 2 layers and was very easy and neat lookin and stays cool its some good shit just alittle$$ but worht it best of luck brotha
if i were u id go to the infirmery and read the the slime on my roots thread its long as fuc but itll give u way more ideas of how to fix ur prob
peace stonE

Can we get some pics?

 

[Numboard]

I started getting a mild case of root rot because my water temps were too high. Once i brought the temps down and added a little hygrozyme it all went away. You can beat root rot its just a pain in the arse depending on how bad you have it

 

[Haps]

There are degrees of root rot, and I would agree that the worst of these where the plant's health is bad might not be worth saving. But, if the plant is healthy still, it is quite easy to bring them back and flower and clone for years, I have done so. JF, these are good techniques to learn, trashing crops costs time and money, fixing them just takes some effort, and some time if the health is impacted.

I was really bummed with rrot my first year of hydro crops. I started, and still do root exams after each crop to learn what works and see when root health is affected. Rrot mostly starts with a bit of organic matter decaying, but can also stay in your system in tubing, or anywhere that is not sterilized between crops. Bottom line is start clean, do the root rinses, develop clean maintenance habits, and you can prevent this from impacting your grows.

Or you can buy shit and put in your reses forever, and worry about it.

Personally I wouldn't bother learning how to save plants that will not yield well. Sounds to me like the mother was unhealthy and now the clones are. pop new seeds.

 

[blank85]

I dont have seeds and cant get clones.

I went ahead and soaked them in diluted 3% h2o2 for 45 min and transplanted them into coco. Most of the roots were white just say 4 or 5 had some light brown on them.

They all looking pretty miserable right now and have no idea if they will live or die.

Will take pics now and again in 3 or 4 days and post the results.

Thanks for all the replies people.

p.s i have lost 7 plants so far including 2 today.

Ok here they are.

 

[blank85]

meh 2

meh 2

And the rest...

I also added some Flora series nutes, as per their directions. Gave them the "cuttings" strength.

Start over......
