You can brew with just EWC and if possible some product containing bacteria. Then you take a cup of that tea, put some ZHO in it and pour on the roots. That way most funghi will come into contact with roots.

I just finished brewing my first ever tea. what is all the gooey stuff at the bottom of the bucket? i thought it's leftover sugar but doesn't have sweet smell at all. Don't think it's worm crap as my ewc still feels like soil inside the pantyhose. Below were what i had.

2 gal tap water sit 36 hrs prior.
1 tsp fungi perfecti mycogrow soluble.
2 tbsp of local ewc.
1 tbsp grandma's molasses.

brewed the tea for 60 hrs. Anyone have the same gooey shit?

Yep, that goo, (called biofilm here) is perfectly normal. It is, just like the foam, a sign of good biological activity.

Why 60 hours? 48 should be enough.

I just wanted to make sure the sugars been used up. The goo is just a bunch of microbe right? Can I just dump the goo in dwc res?

Can anyone tell me if you can replace the ZHO with general hydroponics subculture m? My hydro store is currently out of ZHO for 2 weeks. Thanks

That goo is a mix of microorganisms and their excretions. It's a good sign that microorganisms are alive and feeding nicely. I brew without the sock, so in my brew slime and ewc particles form a mass I filter out, but I think you'd be perfectly fine dumping it all in.

I never brewed for more then 48 hours as it was said microbial activity and diversity peeks at that time and most sugars should by that time be used up.

@Hollway, yes, it seems like a very similar product.

Thanks Heisenberg and gang. I had bad root rot. I trimmed away the brown roots and used h2o2. Waited for a week. Slime didn't break out but the plants were not growing new roots. Just apply the tea 4 days ago. Last night I checked there were bunch of nice white fuzzy little roots coming out of net pot. The original roots are still dead dangling around and the fan leaves still shows bunch of deficiencies. But I can now see first hand benne tea kicks h2o2s sorry ass any day.
Now can I just leave the dead roots in there? Is it better to cut of some branches to encourage root growth? Will the new live bennis consume dead bennies? I'm afraid old tea in the res might cause root slime break out again.

If roots are dead and decomposing, definately remove them. You don't want decomposing stuff in there. However, if they are still firm when giently pulled, I'd leave them for a while and see if they recover. Branches I wouldn't touch unless the plant is wilting (spending more water then it can consume). When plant has a deficiency, it starts using up some of the leaf tisues as an emergency supply (thats why you see yellowing with nitrogen deficiency for example), so having a leaf mass might even be benneficial.

Bennies should be easily consumed by other bennies and shouldn't be a problem. How often do you change your res?

I changes res once a week but its pain in the ass when I have 10 dwc res. I think the old roots are pretty much dead but also kinda firm. Here are pictures of 2 plants' roots.

Photo isn't very clear. What makes you think the roots are dead? I'd leave them alone.
Well those brown roots are not growing longer and stopped growing secondary roots. Not sure if dead. Will they break off themselves eventually if dead?

Yes, if they are dead, they should decompose and fall off soon enough. By now I'd expect them to be falling apart on gientle pull. When plant is in shock it's often difficult to say what is dead and what is not, so I would sugest a conservative aproach.

I think I'm just gonna leave the old roots there to be safe. Looks like the microbe is leaving off of the old roots. Got a thick black gooey thing attached to the roots. Does it mean the roots are dead and are being consumed. Here is the pic from this morning.

hey guys, i have had a serious run of slime and other crap, tried the tea in the beginning, had all kinds of problems, and fought it off in the end with the physan 20 and dm zone. I am sterile right now, it has been about 10 days since i have seen any slime, and i am going to do a res change after i get an answer on a few questions.

I have two 33 gallon rdwc systems. A central res, with two 10 gallon rope totes, piped with 1" vinyl hose, and recirculating with a 396gph pump, that falls back into the res. I did have two airstone in the res, but removed them. I have 4 large pop can airstones in each 10 gal container. These setups are identical in design. They each have a 70litre pump that splits into 8 lines, and feeds the 8 stones in the buckets.

When i started all i had was a 15l 4 site pump and 2 stones in each bucket, and another 4 site that gave two lines each to the res's. Hope that made sense.

I was getting slime and used the h202, but really wanted to use the bennies. I brewed a couple batches and tried using it but got blasted with a biofilm of some sort. My ph went to 4.2 and i dumped the res's and cleaned did all the normal things, boiled airstones for 20 min then put them into h202 bath etc. Refilled the system with the bennies and nutes, and things were back on track with nice new roots growing. They started eating well again and i added some kool bloom and big up powder and the next day i had the worst nastiest crap on my roots i have ever seen. I don't actually think this was root rot, i did at the time, and treated with physan 20 for 24 hours at the emergency dosage, and then broke down the systems, cleaned and sterilized everything, replaced hoses and fittings, made new manifolds etc and bought a chiller for 400 bucks.

But the reason i dont think it was slime or root rot was because it seems that something happened with the nutes, that created a reaction, and forced all the color out of the gh micro and bloom, and got really thick, like dried marroon colored plastic. It was nasty. took a lot of flushing to get it off, rinsed under hose in shower.

These are the same roots, same plant hours after adding the big up powder, but i also had sm-90 and superthrive in there at full strenght and i heard they react somehow.

Anyway i have read this entire thread and the same hiesenburg threads on other major sites, and liked this one the most. I have the cyanno in my well. I use ro filtered water at 3 ppms to start. I have just about everything for roots lol. Aqau shield, great white, orca, voodoo juice, rapid start, thrive alive red and green, superthrive, Ancient forest, etc etc.

I havent used any since i got the first run of what i thought was slime. just gh 3 part and the micro bloom formula at 120 mls micro and 180 mls of bloom in 33 gallons. I tossed one of the plants in the other system and removed a bucket from ther system and mixed the nutes for that res accordingly. I also used 3ml's of physan 20, and 1 ml per gallon of zone, and have been running very consistant numbers. Ph is staying right around 6, with a drift up to 6.3 or so over the week in one res, and rock solid in the other from 6.0 to 6.05 over the week. The ppms have gone down a little and they have drank a few gallons of water this week. I have the chiller running, and the water has been staying between 63 and 69.

The problem is is that i have not seen any real developement in the roots at all. They are as clean as i could get them, and they were really matted together, so getting to the center of them is impossible. I am seeing a few new fuzzy white roots in the net pots well above the water line, but that is it. So i am wondering if this root mass is just dead, or what?

The plants exhibited every defficiency there is, and i have removed a lot of leaves after the root issues, thinning them out a bit, and they look pretty well considering their trip. The best ones are very green, just not growing really, however they are in flower and the hairs are coming, and lots of preflowers.

But the roots worry me, they seem to be just laying there, no growth, no stimulation at all.

They pretty much have stayed the same since these pictures.

Can I post a link to another site where i have a journal for reference?

What i am asking here, is for hiesenburg himself to take a look, or any of the many other guys i have seen giving sound advice, and there are a ton of you, to answer a couple questions and give me some guidance. I have spent a small fortune on this room and setup, and want these plants to finish the best they can.

I would like to know what the heck happened when i got that nute seperation, and what happened. I have tons of pics i can upload and anyting else you wanna know just ask.
I would also like to know if it would be a good idea for this next res change, to follow the tea route again, to get my roots growing again, or if they are too far gone? I have tea brewing and it will be 48 hours when i change the res, clean, sterilize, dry. Then Ro water and tea for 12 hrs, flushing plants during this time with flora kleen, then ro water and tea, and then add the plants back to the system, waiting on nutes at half strength for a day or two?

Does this sound right?

Sorry if this seems to be a ramble, but there is way more info than i could type in a short sentance. I just wanna know if this would be a good idea, to get my roots going again, and if its worth the risk?

10after420, I can't tell you what exactly happened with your res, but one pattern I have found on this forum is that almost every time someone comes with a slime problem, he a) uses GH products (floranova is a no) and b) uses bunch of aditives. For one, superthrive has been reported to cause problems in DWC and rapid start, thrive alive and big up are all at least part organic, so if you used any of these together with EWC tea, trouble is almost guaranteed as bacteria will eat those organics, multiply too much and slime everything up. Also, exact contents of each of those products is a secret, so you can never know how they'll react together.

My advice, don't play the aditive roulette. Brew some tea, pour it over the clean roots, make a fresh res with nothing but pure inorganic nutrients and watch what happens. You might be suprised.

Ya that is my plan. Just the micro and bloom, and Tea. But what i really wanna know, is since my res is sterile, and i have a solid ph and ppm reading now, should i just keep going with what i'm running? or go ahead and try the tea, to get my roots going. Idk if they are dead or what is going on, they just seem really relaxed, not like nice fluffy roots, and they aren't growing new roots at all below the water. I am wondering if it might be worth a try with the tea to kick start new roots?

Thanks for the reply by the way!

No problem :)

Could you separate just one bucket and experiment on it?
yes. I have one in the 2nd rdwc system. its the worst hit of the bunch. I could offer it up for sacrifice, just was hoping for a more clear answer on if i should try it. At this point i am less and less concerned with yeild. Im a week into flower, and while they are attempting to stack up some nodes, its lookin not so good. So if taking the risk will save the two big ones, id do it.

The last three pics are the blueberry plants, and the ones i would sacrifice in an experiment lol.
Heres a pic of them before the root issues. The smaller ones are the trainwrecks (the ones in that nasty root pic earlier, gone now) They were doing so nicely. I can hardly believe they look as good as they do. They have lost so many leaves!

001.jpg040.jpg

This is what one full system looks like. The other is to the left, and just has one of the buckets removed so i can use it for one set of plants. That bucket pic shows how dirty the res got in about a day when they got nailed with the seperated nutes and biofilm. It makes me wonder soo much, what the heck happened.
