A lot of stuff can be grown in tubs or growbags.

Yes, there's the cost of getting it and tending it, but there are advantages in positive mental health and exercise (with bigger yards) and some hippy "feeling connected to the world" stuff.

Eatings peas just off the plant is great.

Even herbs and spices can be grown if you just have a window sill.

But, yes, it's not for everyone. Some people just don't like that kind of thing.
