I've tried sag, hydroguard, Piranha, hygrozome and h2o2.
The Piranha at least helped but the others did nothing. Think I'll start using h2o2 as a preventive in the future though.

people refer to root rot as "pythium", but in reality, there are dozens of pathogens that cause it, some of them are systemic, and some are not....Pythium isn't actually systemic....it's a parasitic fungus that lives in soil and eats plant roots from the inside out...so is Armillaria, and phytophthora cactorum. these aren't systemic, and can usually be gotten rid of with peroxide, bleach, or fungicide.
burkholderia, xanthomonas and pseudomonas are bacteria that can cause root rot. if you have one of these, they ARE systemic, and will infect any clones you take...
the good news is you're much more likely to have one of the fungal causes than one of the bacterial causes. the bad news is, you need to clean the shit out of your room, which ever it is....

I will be watching my roots obsessively for now on.

Oh believe me I plan too.
K so maybe I'll keep moving forward with my cuts for now but I'll plant some new seeds today as well just in case. By the time my seedlings are old enough to take cuttings from I should know by then if my cuts are infected.
I'll be extra careful and sure not to cross contaminate in the mean time.

Nothing except high levels of chlorine worked to kill the infection for me.

I've been working on this so long that I'm at the giving up stage and starting all over.
Just out curiosity though what brand of chlorine did you use and how much? I threw all my infected plants out into flowering today and just gonna try to make the most of them while I work on cleaning, disinfecting and getting fresh plants going in my veg area.

pool shock works, and so does non perfumed, plain bleach. 2 grams of pool shock in a gallon of water makes a stock solution, you use 20 ml or so every couple of days to keep things sterile, may use it daily for a few days as a "shock treatment" to knock it down to begin with. 4 to 1 makes a stock solution from liquid bleach, i put 20 ml in a 100 ml beaker, fill it with ro water,and use that as my stock solution, at the same rate as you use the pool shock solution

If you want to do it by the book you need an ORP (oxidation-Reduction Potential) meter and a reading (concentration of chlorine in water) of 680 mV or higher. I used calcium (note: not sodium) hypochlorite (aka pool shock from Canadian Tire). I did not use a meter, I did a rough estimation of PPM using the below formula I found.
Then I adjusted that formula to above 2 PPM free chlorine.
And I kept the ORP (free chlorine if you don't have a meter) up until I started to see white roots again.

i find it interesting that they mention 3 species of pythium and fusarium and rhizoctonia....told you...many causes of root rot...pythium has just become a name for the condition....

Can't lie, I'm kind of stoned right now lol. So long story short I would add 1.545 g per 100 gallons? That sounds like such a small amount for that much water.

I figured their was many causes of root rot. I assume that's the reason why some stuff works for some people and not for others.

before you do that, is it possible to buy a few cans of insect fogger and fog your room first? make sure you got rid of the fungus gnats first.
and i would definitely try to take clones. worst thing that happens is that they get rot and it would save you time from starting from seeds

I keep learning from this thread. Good info man.

yeah...fungus gnats are prime vectors for spreading the many types of fungus in planters, both beneficial, and not so much.

me too....

Yes I certainly will fog it up. I used Gnatrol to get rid of the gnats but it's certainly not a bad idea to bomb it anyways.

what was your max ppm of free chlorine?
i ran at 3ppm to be in the safe zone for the plants which i've read can handle 5 no issues

Very high I don't know exactly because I don't have a meter but probably around 5 at least. If I recall correctly they can handle up to 50 PPM per Jorge Cervantes...?

holy crap. that seems way high.
i know 5 ppm is safe for human consumption so that was my limit.
