Brown slime on roots in UC

Miggs · Jul 26, 2013

This is my first uc run so I'm expecting some problems but was not expecting slime in there. These went in 5 days ago from my aero cloner. Feeding hydro grow, calcium nitrate and Epsom. PH 5.7 EC .6 water temp 63.

They're just getting to where I can see new growth daily. Didn't see any of this yesterday, found it this evening. Is there something I can add to clear this up?

Some Under-current users may disagree with me, but I have used Hygrozyme and run it a 2ml aka 1/4 strength. It worked wonders for me. Also wouldnt hurt to be some reflective material around the plant base and on the grow stones

I think you can get some stuff that is ment for fish to keep from getting rot but I spent a lot of money and time trying to do the same thing.i hate the under current.tryed everything else.good luck

I tried turning the chiller down uv sterelizer all kinds of stuff physon 20 bleach h202 and a lot more no luck with anything.

look into CAPs bennies, ogbiowar.com.

Texas Kid · Jul 27, 2013

CAPS bennies and some insecticidal soap will more than likely work

Miggs · Jul 27, 2013

Thanks all. I have CAP's bennies on the way. Think they will be ok for a few days or should I treat now with something off the shelf and the do a water change with the bennies when they arrive?

Texas Kid · Jul 27, 2013

I would still use the insecticidal soap to knock all that slime off...Home Depot has it for $8-$9 bucks

Capfan · Jul 27, 2013

When your bennies arrive, drain res, reinoculate the new water then dump it into your UC.

Ive heard nothing but great things about the new Cap Bennies, not sure if its expensive or not, but you might run through alot of it to beat the root rot, perhaps?

What im gettin at is, Bubble your own Tea, over load that rootrot with bennies!

edit: What are you using in your UC atm? if no bennies, you Zoning it? H202 ?

Never personally used the Hygrozyme in UC, ive read multiple threads that this amplifys the situation..

Nothing in there now except for the nutes.

I was skeptical on it too because I had read many threads before starting the UC that Hygrozyme had made certain situations worse, but been using it now for the past year with great results in my veg and flowering when and if I need it

TK. how much insecticidal soap would you recommend per gallon?

sealed138 · Jul 27, 2013

I've used hydrofungicide before and it worked pretty well.

I got slimed earlier this year by being lazy and not using anything in one of my systems for 3 weeks. I saw the slime start, and put off taking care of it until it got to pretty much all of my plants.

Here is how I won. It was easy.

First start a tea. Fill a 5 gallon bucket with 4 gallons of water (tap is fine but you need to bubble it for a couple hours prior to adding bennies to get the chloring out. Add 20mL unsulphured black strap from the grocery store, cup of EWC, 1 tablespoon OG BIOWAR root pack( www.ogbiowar.com ). Bubble hard (I now use an eco5 air pump by ecoplus and a 6" air disc). After 24 hours, tea will be foaming and ready. Unplug air pump. Let settle for a minute to let the talc carrier and EWC chunks fall to the bottom. Scoop the water from the top and use it on your plants and in your res. A 1/2 gallon pitcher will easily fit in a 5 gallon bucket for collecting the tea.

1) drain the system
2) fill with tap water. Add 16 drops of clorox bleach per gallon of water. let this run in the system for 2 hours.
3) drain and refill with tap again.
4) add physan20 at the rate of 3mL/25 gal of water. Let this run for 2 hours. DO NOT forget about draining this one after 2 hours. It is toxic.
5) Fill with fresh water. Add nutes at no more than 1.0EC. pH solution. Add tea @ 1 cup in to each plant site crown, and 1 cup per 5 gallons in to epi.

6) follow up with solution changes and tea weekly for remainder of cycle and all future grows.

My slime is gone. New roots started popping out in a week. I could have done better without the slime, but at 4 weeks (a week after being slimed), my plants looked like this:

And now they look even better. No signs of yellowing, shoot die back, stunted growth.. etc.

I would suggest Caps Bennies for sure, however instead of filling your system with a bunch of different chemicals what I did my first grow was take out each net pot 1 at a time and dunk the net pots into 3%h2o2 you will see the slime bubble away... Here's exactly what I did...

1 at a time dunk each net pot into a bucket of H2o2 3% (from pharmacy).. Dunk pot for about 5 seconds.. Then dunk into a bucket of fresh water.. Repeat this about 3-5 times each time with a new fresh bucket of water h2o2, new water,h2o2, new water ect., until you no longer see the roots foaming... Drain out your UC and fill up with fresh water and Caps Bennie Tea and you'll be good to go... This is a very gentle and effective way to get rid of the dreaded slime early in a grow... I wouldn't use this method if you have a bucket full of roots, but it works wonders on a small root mass

Also IMHO your water temp is too low... I like to run mine anywhere from 66-68 when I can.. However my run right now my temps have been 68-73 and with caps bennies my plants have never grown faster or stronger.. I wouldn't recommend your water temps get that high but I can say I've had great success this round with my temps high... Check out my thread in capulators beneficials forum if u want to see them in action

I've run my RDWC as cold as 55F with no ill effects. In fact, I would be willing to bet that if you can get your RDWC water temp below 60 that would kill the slime right there. It would make the water too oxygenated for an anaerobic life form to tolerate.

I don't know how people can run sterile RDWC for any length of time, I always had problems with opportunistic bugs trying to fill the void left by sterilizing the root zine. Only when I got the water cold and built up a local population of beneficials did my RDWC systems stabilize. Now? Rock solid, even into the 70s in the daytime.
