Your orchid requires a LOT of light but not direct sun. Also, high
humidity is important. But do not over water. Too much water will
cause the roots to rot and you will eventually lose the plant. Do not
re-pot until there is absolutely no room left in the pot. You can tell
that by doing the squeeze test with the root ball. Take it out of the
pot and give it a gentle squeeze. If you can get it to give some, then
there is still room in pot. If it is tightly packed, then it is time to
re-pot. You can add a little orchid food to the water and feed weekly
weakly.
