I just purchased a tower garden which is sort of growing plants vertically. I started on March 26, 2018. The Tower is located in the front Garden. I am growing some herbs and some vegetables. For starting these are some of the plants I am growing: tomatoes, peppers, squash, eggplant, Swiss chard, oregano, flat leaf parsley, lavender and some others.
With this system you can grow vegetables indoors with grow lights in the middle of winter.
