My Vanda's down to 3 leaves

[Fredmax]

Alas it was no good, I checked on the plant in the bag and it had developed white fur around the crown. I picked it up and the three leaves slid off

I'd love to know how sphag in a bag works for so many?

Fred ----- I've never used that method before, but I'm sure that the orchids that pull through (recover) had probably stabilised - as in their health wasn't taking an extra bad turn due to fungal or bacterial activity or something.

The great thing is you tried and put effort into saving that orchid. For that - I hugely commend you!

To really up the chances for super long term orchid health ----- I have seen plenty of longevity in orchids by providing suitable temperatures and lighting levels (and lighting duration), satisfactory humidity, gentle air movement through the growing area, with an airy enough medium in very good drainage pots ----- and suitable watering schedule plus fertiliser/mag-cal schedule.

I think your growing technique is pretty good too already. Could it be just not enough air-movement in the growing area? Maybe that's all it is. Air-movement can really help cut down or even eliminate some major nasty stuff - namely bad fungal and/or bacterial activity.

bummer, man

16 C/60 F is stressfully cold for a Vanda. Healthy ones survive night excursions that low if it gets warmer the next day, but they don't do well constantly that cool.
