I had root rot from using nutrients that I was told would work in hydro that did not.
I ended up cutting everything around the net pot. I had way more roots than that.
I sprayed with clean water then soaked in water/peroxide bath for about 10 minutes then sprayed with fresh water again.
Then cleaned and filled the Rex with a light feeding something like 150-200 ppm and adjusted ph to 5.8. Also added about a half dose of fungicide also.
It took about 4 days before I noticed new roots finding their way back into the Rez. I did fill the Rez up to almost full so the roots that were in the pot would be in water and grow back.
And that isn’t wrong, but your plant is severely stressed and we want it to breathe easy. If you can vary both temp & RH, adjust as you see best/easiest. Shoot for VPD 1.2 zone, slowly as suggested. They need to send out new roots seeking water, so keep the Rez at least touching the net cup.
Check EC, pH & water levels after you get things sorted out then they’ll tell us what’s going on.

So someone asked in another post what my setup was so I posted my video before I moved the plants into it. @GrouchyOldMan asked me to post the vid over here so here ya go guys, not sure how I forgot to post it here before
Wollastonite, hmmm, that’s an interesting suggestion. I’m trying to control Ca, Mg and Si separately and Wollastonite (calcium inosilicate) might not fit into that goal.
Do you see specific silica specific results using Wollastonite?
Calcium Silicate is used often to supplement silica as a dry amendment.
It fits in with coco and I have used as high as 100grams/3 gallon pot and seen no difficulties.
My branches and stems are definitely thicker and sturdier.
Since I use the rez for like 3 weeks at a time, it fits in perfectly for my needs to supplement silica.
Looks like you cleared up the root rot/brown goop with the UV light?
I was gonna say, calcium hypochlorite is what I use and would keep the res clean. Usually comes as a dry powder. Pool shock in pinch. 2grams in a gallon jug makes the concentrate solution. Dose 2ml of that per gallon of res water, every 3 days or so and you should be good
This plus a Home Cheapo 3.5 gallon bucket would make a pretty credible OctoBucket. Drop in a few bulkheads, string some tubing to your “pots,” plug into your “ammo box” and a tall reservoir and you’ve got a small cannabis farm!..
I really like the 3.5 Gal.
I feel like you could easily fill with roots after a 5-6 week veg. Has anyone experienced root intrusion out of res w Micro? I recall that was an issue w dwc 5 gal buckets auto feed long ago. Had screens over the bulkhead to combat.
I think the octopot works well because of the mixture of air and water in the rootzone beneath the plant.
The media pot size does not really matter to me as the media is inert and useful only if you are adding a dry amendment like gypsum/wollastonite.
Other than this, the media container should ideally be tall and thin, so it encourages the root to hit the rez azap.
Something like
Regarding the water level in the plant tub, I think having a low level of water encourages more fibrous root growth once the roots reach the tub and more frequent changes of water in the tub.
Having a dry period between rez refills also works well.
