You might find this helpful. Maybe you've walked into a small apartment and seen flowers in vases? That's exactly how you should grow your vegetables if you have no space. In vases/pots/containers. But thing is, you can't plant just any kind of vegetables in pots because the yield may not be worth the effort. The vegetables that would do well in pots are leafy greens [kales, lettuce, collard, etc] or maybe scallions/green onions.
