Sorry to hear of this accident! I worry about losing electricity/heat (and have at times past). Hopefully, some will survive but a huge loss none-the-less.
That’s quite unpleasant case, keeping in mind that I can “frozen” orchids without low temperatures. Each winter the survivors are few (too much fert, water etc). I envy you - with an accident a hundred orchids unlike I’m struggling to rescue 4 or 5. I’m trying to show support actually.
