I think this is a fairly valid point. From my own anecdotal perspective I don’t much like “gardening” but when we wanted to grow vegetables we did research enough to know that this product is basically a waste of money. If you want a self-watering system you’re going to go with that, and maybe even have some fish for cleaning. If you just want easy low maintenance vegetables you can build a raised bed and water it with a hose on evenings during a dry period. That’s basically all you need to do.

I’ve removed a ton of weeds from between our tiles, I’ve removed exactly three from the raised bed. The watering takes like 30 seconds a few nights a week. The real trick is to plant something with a high output and no maintenance required like squash.
