I do not have a balcony, but I thought I would share the videos I have collected in the past just in case they ended up helping someone. I just joined, so I am not sure how/if they can be embeded, so I will just put links.

Also, here is a website that might help.

“If it is a South or West-facing balcony, you’ll have sunshine almost all day, which means you can grow anything. An East facing balcony receives sunlight in the morning, which is sufficient for most greens, herbs, and root vegetables.
On the contrary, a North-facing balcony usually remains shady throughout the year, and it isn’t easy to grow vegetables in the shade. However, you can still try lettuce, parsley, peas, cilantro, fenugreek, green onions, bok choy, and mustard greens.”
