Do you happen to know what kind of orchid it is? A picture will help. Sounds like you were right to remove it from its pot and sphagnum moss. I would not fertilize until it recovers. Would need more information on kind of orchid to speculate further.

It's a phal. That's all I know. Can't identify further till it blooms. Here's a pic about 4 days later.

It is best if you try and find some complete culture notes written for where you are in the USA. At least then you would have some idea of Optimum growing conditions.
As far as humidity goes....too much stress is put on that and it is the cause of much overwatering.
From what i can see of the plant it is in fairly good condition and it should survive. Maybe you are in a part of USA where summer culture is outside and winter culture is inside?

I haven't really been able to find local area culture notes. However, I do know that spring and fall in my area are okay in shade and summer with a shade house with fans. Our winters only see maybe a week or two a year under 50. In the winter I will probably just move them inside. The little stringy roots that have lost all the cover on them I figured were dead... but they are the ones reaching up towards the leaves now. The fatter green roots are going down. and the tips of them are white with new growth. I am pretty confident the plant will survive as long as the humidity stays good. Humidity here rarely drops below 60% outside and goes higher at night. I am still pouring some water over the roots about once a week but it falls straight out the bottom of the hanging basket. ( put a hole in the coconut husk basket to avoid massive water retention.

I'm not an expert on orchids but those baskets can have moss on the outside of them. That's why the sell those metal cages. Not sphagnum moss either- green moss. That keeps the liner wet.

It is a brand new basket haven't seen any moss on it yet. I have been checking for that though.

No that's not what I meant. You take the fiber pot out of the metal holder and turn it upside down; then you put WET green moss on it; then you but it back in the metal holder. So the moss is keeping the fiber wet but not actually touching the roots.

You just buy the moss and soak it.

Looks fine to me. Keep doing whatever you are doing.
