Based on your User ID, I have to ask if you are in Florida? It makes a huge difference. A shady, northern lit balcony in Florida gets more light than some areas of the country. I have a covered deck outside my kitchen that gets southern, western, and northern exposure. In the winter, I have all the potted herbs, etc. on the southern side. About May of each year I move them all to the northern side to a spot that gets no direct sun but gets plenty of light anyway. The summer sun kills them off if I leave them on the Southern side and I would never put them on the western side.
