I plan on having a potted garden on my balcony this summer.

For the time being, I'm really wanting to start growing some herbs indoors. Definitely some basil, chives and cilantro, and some other types maybe. The only problem is, the only decent window I have faces North and I have a feeling this isn't a good spot to get maximum sun exposure in the winter. I also have a really small window that faces east.

Anyone know which one window would be better to grow my plants at?
