Interesting. It is important to know where the windows face and then what blocks sunlight (trees). I love an easterly exposure best, followed by southerly, then westerly, and (dead-last) northerly. During the late spring and summer months you have to be really careful of the sun coming in from the west. This mid-late afternoon sun will cook plants! There is typically not enough light to grow/flower plants well when the light comes in from the north.
