Thank you for the visit and your kind encouraging words.
I grow my orchids at sea level and very humid and hot in summer. Whereas you are highlander with dry atmosphere all year round. I have visited Colorado twice; once in the middle of winter for snowboarding and in summer on tour for a broadway musical as a designer backstage.
You have a totally different zone, therefore you have to adjust to your environment to provide a comfort to your orchid plant.
Always take note of where your plant came from (labgrown or orchidgrowers place) and where it is endemic from. Your plant is from the equator area which is hot and humid. There are two seasons=the dry and the wet monsoon rains.....as opposed to our Temperate zone with four seasons. Since you inherited that orchid plant already thriving in our temperate zone then it is acclimatized....yet you still have to follow the two seasons of the equator in terms of watering and fertilizer needs. I do not give it dry period since morning dew and high humidity provides the plant moisture in its dry seasons....so I water it the same ways in winter but do not feed it fertilizer in winter. Additional electric lighting and an electric humidifier with fan is advised all year round.
You may repot your plant any which way you want. But my lavender spotted foxtail is in a four inch basket with its pencil thick roots intertwined on the basket and I dare not repot it. I soak it overnight in a basin of water every other week.
