| I agree orchids can grow in almost anything.
Many of my Hawaiian suppliers use coconut in all its forms, but with a few provisions.
The quality of coco Husk can vary greatly. All have some salt - some more than others. If processed too green coco can leach sap that orchids seem to dislike.
All are a sterile mix, which is the source of my dislike of the medium. There is not even the minimum of beneficial microbes to start a culture. I believe that nitrogen setting bacteria are necessary to re-formulate the Nitrogen into a form for the plant to absorb into the root system.
I am not discouraging anyone from using coco. It can work very well. I would agree that it should be soaked to remove any salt and you should add something to the mix to get the beneficial microbes started. Like anything always buy the best quality available.
