Hello so I've had root rot now for the first time, a flood and drain system. I'm wondering though do all the fungi that cause it, Pythium, Phytophthora, Rhizoctonia, Botrytis, Alternaria, Fusarium exist all around us anyways but it's just giving then the conditions to take hold that creates the root rot? I'm asking because I've gotten some water off a plant I was rinsing the roots off, seeing what would happen if I tried to save it, onto a cutting in some perlite, it was fresh water I'd already rinsed the roots before, this was the 2nd time, but I'm wondering if I don't give the fungi the opportunity to take hold by their favoured conditions will that cutting be ok or is that messed up now too? And for that matter any other plants that had been in contact with the water that had the plants with root rot, are they all doomed or if I don't allow the conditions for the root rot to take hold can those plants still be ok? I've read about people talking about contamination but some of my plants from the shared res and flood trays are still looking ok, it's been a week now too, I turned the res watwr temp down to 14 degrees celcius, put a bunch of calcium hypochlorite in the res 2 days in a row then more on the 4th day, not watering during lights out at all and less during lights on and it seems to have stopped the spread of the fungi.
