Watering orchids in bloom

[bkim]

I've heard you shouldn't get water on buds or blooms when watering. Is this the case for all orchids or are some more susceptible than others? How does one go about watering plants that you typically dunked or showered in the past when the inflourescence is so close to the plant? I'd think it's ok to get them wet considering in the wild it rains on the entire plant, not just the roots.
