That’s only if you dislike gardening. If you like it, you gain happiness from it (the opposite of a job). Once you have everything set up it’s not that much time and money. It’s like anything else, you get used to it and can eventually spend maybe 10 minutes per day watering (less if it rains).

Also, the food you get will taste much better because it’s picked when it’s ripe. Most vegetables in a grocery store are picked too early.
