How Do You Quarantine New Plants?

[lycaonpictus]

Not sure if this is the right forum, but seemed as good as any.

As has been mentioned elsewhere, we're getting into Orchid Show season, which means I'm hoping to add some new plants to my collection. I shame-facedly admit than, in the past, I have not been good about quarantining new purchases. Since the consequence of my bad habit at least partly contributed to losing a majority of my collection to scale a few years back, I'm determined to be more rigorous this time!

So how do you quarantine new plants? For how long? In the same room with some separation, in or in a completely different part of the house? Inquiring minds want to know.
