I’ve been a gardener for so so long and can tell you that the article’s suggested small space isn’t possible unless you want to be battling mold, bugs, and disease. You need space for airflow, space so disease doesn’t spread, space to look on leaves for pests… Neem oil, spinosad, monterrey disease control, BT caterpillar killer, copper fungicide, they’re the organic stuff that’s safe to eat (and use on cannabis plants) and they’re all WAY more expensive than tomatoes, lettuce, beans, etc.

Not discouraging gardening, it’s incredibly therapeutic, useful, and satisfying; but it’s rarely successful in a small space.
