I know that I should not use tap water, but what about bottled
water? Hopefully for only one or two waterings!

Thanks

I have very little experience other than with phalaenopsis. All I can
tell you is that for years I have been watering them with cooled water
from the hot water tap when rainwater wasn't available (which was fairly
often until a year ago). We are in an area of very hard water, and it
does not seem to have bothered them too much. I have one paphiopedilum,
and that similarly doesn't seem to mind too much.
