        Good plan so far. See below though.

        Well, these plants have been grown in very 'soft' conditions, ie:
extremely high humidity. The leaves don't have a chance to toughen up and
will, as you've experienced, wilt when exposed to regular air humidity.
You are right though in that the domes aren't beneficial as they will lead
to fungus. So, what to do? First, take them away from the south window.
If they're not already dead, they soon will be baked in the heat. Place
them in a well lit area which is out of direct sunlight. Secondly, leave
the dome on and slowly remove it over a period of a couple of weeks so
that it slowly becomes accustomed to your climate and indoor conditions.
Once acclimated to your humidity, then you can gradually move it closer to
the window and direct sunlight.

        The moral of the above? Plants respond poorly to rapid changes in
their environment, so care must be taken to account for this. Hope this
