It doesn't change any of the prior answers, but for most phalaenopsis that's a bit too much on the cold side. And if your space was that cool when you brought this one home, and it appears to have not been doing well anyway, it could likely have been the tipping point for its demise.
Having said that, my phals grow for about three or four months of the year with lows around 65F days around 71F. They may occasionally have a few days with a 60F to 68F temp range. BUT, they have a higher temperature range the other 8-9 months of lows in the 70s, highs in the 90s+. They are adapted well.
But if I brought in an orchid with failing roots, that's a whole different story. I have to baby it with more "perfect" conditions until it gets vigorous again. One of your steps toward educating is to look at pictures or plants and learn what the characteristics of a healthy plant, good roots, etc,,are before purchasing.
