Stupid question, I know...

[Skayc1]

so in the room I have my orchids is two windows on opposite sides of the room (3 windows really 2 on 1 side) & I really don't know how to tell the direction the windows are facing (not good at that) while I think neither is east nor west, one gets a little bit of morning light, the other 2 gets the afternoon light, the orchids I have are on shelves slightly away from either window. I'm running out of room. I do have a shelf near the window that gets morning light, If I get more orchids would this window be bad? It's either a southeast/northeast window? or should I find new shelving for the between areas?
