Hi Sandra. Mostly what your going to hear is Phals like light but not
too intense. Try a sheer curtain that lets light in and it'll probably
be ok. I have phals. in an east window and use a plant light above them
on cloudy days and they're doing fine. I once heard someone discribe
how they held their hand above their orchid to see if it cast a shadow -
that way they could tell the degree of light it was getting. Good luck
and remember your window might not only give too much light but also
heat. Your phal. will dry out faster.
