Brown mushy roots in coco coir

Hi new to forum here,

I am growing in coco first time. Great growth up until I transplanted from three gallon to ten gallon pots. Couple days later I noticed the roots were getting brownish and a little mushy. The coco I transplanted into had been wet for three weeks in a black trash bag. It must have grown some funky bacteria in it or something.

I flushed them three times with five gallons each of water with 5 ml per gallon of 35% hydrogen peroxide over a day. The next day (last night) I watered them again with water with 5 ml per gallon hydrogen peroxide. I am pretty sure the medium is now sterile.

How would I go about using beneficial bacteria to get them back on track and prevent future problems? I got a bunch of stuff to do it with.

Aqua Shield
Actinovate
Organic worm castings
ZHO beneficial bacteria/fungus

My friend told me how to make tea, which I have brewing. He gave me a gallon of his tea he had brewing for two days.

Does the tea get rid of the mushy roots? What is the treatment plan? How much do I give them to bring them back?

The tea definitely works, I'm using it now. Not sure how to use it for recovery though.

Nobody here uses tea with coco? Hmmmmmm.... I will just keep using the H202 then.

How much perlite do you have in your mix?

I use tea's in my coco/perlite pots with no problems. I pretty much do everything you would do with soil but with coco. I use a mix from sunshine so it has bene's in it already to start off.

The tea your making will help your plants recover. The bene's in it eat the root rot and get the plants to grow new healthy roots. If you look in the DWC section it is stickied in there on how to get rid of slime. Its the same tea.

You can brew tea..... I use orca


on a side note for storing coco

after you strip the roots out after you chop down soak your medium in cannazyme or any zyme product
for 2to3 days then allow it to dry out! Then store in a bag.

the tea recipie looks like hiesenburgs, i have used it in flood tables and it worked for me. that said 3g to 10g is a big move. if the coco you added to the new pot was realy wet that could b your prob. i like to prop pots up at a 45* angle to let the excess water drain out till new plants start to grow into their pots. that way there isn't 4 in of standing water in the bottom. flushing, tea, nutes ... before it dries out would just make the problem worse. the nice thing about coco is that like soil you can just let it dry out. in hydro root rot is a disaster, in dtw coco its pretty easy to deal with.
oh with the pearlite im using @ 1/3. i had an issue with the pots drying out a little too much on the sides last grow tho, but i use fabric pots. been thinking about using less, adding vermeculite, or just switching to reg nursery pots to prevent that.

OK, here's the updated scoop.....

I started giving them the tea. One measuring cup full when I water once a day. They just took off like it was no tomorrow. They are now four weeks into flowering and huge. The tea worked wonders! They look fully like hydroponically grown plants, not like soil grown plants. I will get at least a half pound off each one. This coco is awesome!!

Coco does kick ass

What are temps at rootzone level?
