Thanks for the messages everyone.
I deal with root rot occasionally since I'm in the slow process of switching my entire collection over to semi-hydro. When something "doesn't take" I usually notice within a week and by then usually all the roots are dessicated. I always chop everything off to the rhizome (except leaves) and either plant it in spag or a glass with an inch of RO water. eventually they throw out new roots.
Orchids are the most resistant plant I've ever seen. I've only completely lost two plants in the past 3 or 4 years; a hoya with sunlight issues and a $7 phal.. it seems you can make them bounce back from mostly anything.
