Phal need East facing windows?

[ottercottage]

Hi, Jennie, possibly the orchid has been overwatered in the past - that is why the leaf in bottom photo might appear a little wrinkly? Also, if the roots were mushy might be a sign. I would mostly keep phal out of the outer decorative pot and maybe set it instead in one of those plastic pot holders you can get anywhere for under a dollar. Or, on a humidity tray. Also, it's hard to see the exact size of your plant or know the extent of its root mass, but possibly pot down if necessary? I live probably not too far from you in Long Beach, WA and I grow my phals in both the south and east windows, also grow under lights. I water a couple of times a week. I don't mist my orchids. My humidity may be close to yours in winter, around 40%. Because central heating drops the humidity, I have a couple of water fountains in my house and a warm mist humidifier. If you are afraid you'll overwater, add just a little bit of chopped sphagnum to the bark. mix. You'll get the hang of it!
