Phal Yellow Leaves hopefully solved

1. Wow - that's good to know. Shouldn't give up on it if it takes up to a year. I shan't.
2. Good.
3. In a bright window but backed up from the light source (shelf in cabinet - sort of hard to explain but I think o.k.) so sort of a bright shade situation.
4. Humidity dry in the winter - wood burning stove keeps it dry. Should I do a pebble dish with water? Also, in the summer, outside in the shade? Plenty of humidity in Massachusetts in the summer.
Lastly, should I let it really dry out before watering again? The watering thing is really tough for orchids, no matter what people say about their ease of cultivation - or is that the sellers that say that??? At any rate, appreciate your thoughts. Thanks again.
