I have no personal experience of growing indoors or outdoors as of yet, but I have just rented a small piece of land where I plan to grow a few different berries, amongst other things. Mostly for the learning experience, but in the future I plan to live somewhere warm and grow most of the food I eat...

Grow your own stuff. No matter where you live, you can grow tomatoes and most berries indoors. Pesticide free and a great learning experience, and much better tasting than mass-produced supermarket fruit.
