Thank you for the welcome
Some of the orchids that the woman had out were also Phals, and I thought with the sheet blocking the direct rays it would have been ok. It was the equivalent of sitting under an umbrella at the beach. The main problem is, I'm from up north, and not used to the Georgia sun
I thought I was doing right, and now I feel dreadful. Yes, I did move them back indoors, I just want to make sure I don't do anything further to harm them.
Thank you so much for your advice, hopefully I won't make too many more mistakes in the future
