Hello from the Great North Woods of the great state of Wisconsin
Growing Orchids a challenges I have a Sun room gets cool at night usually in the low 60,s I have Orchids for those kind of temps but how wonderful if things thrive even if you do everything wrong.
Welcome! Actually many, if not most, orchids bloom better if there is a significant temperature difference between day and night. Low 60's F is not particularly cold for most of the orchids that you are likely to grow.
