I rotted my paph roots ...HELP

[oborchid]

I recently let a couple of fans in my greenhouse die, and waited too long to replace them. In the meantime, I am afraid that I allowed several of my paph's roots to rot. They are all in semi-hydro.
I pulled one out of the pot and it has no roots left.
Should I use the sphag n bag technique?
I have thiomyl, and I was thinking of drenching them all with it, and then following up with a dose of KLN.
Any thoughts would be appreciated.

it depends on wat you are referring to. if the plants' roots where adapted to the s/h they shouldnt have rotted off. they would be in water--thatz the point. but if itz a new transfer, dying roots are quite normal at first.

which of the above scenario is your case? an old transfer or a new transfer?
