> 100m2 is enough
I would disagree and I think most people who have ever planted crops on 100m2 would. They counted only vegetables and some potatoes, but later they say you need 90m2 (!) of potatos alone. And you’ll eat only potatos as carbs then because wheat etc take a lot more area per kg. Plus most people can’t levitate above their hypothetical 10x10 patch to tend the center crops.

There is zero reason for hydro if you’re planting potatoes. Hydro isn’t that much better than a greenhouse/grow room for most other stuff, except for maybe strawberries and peppers. Lettuce like in your pic can be planted more space efficiently indoors (hydro or not doesn’t really matter), but the trade off for 4x less space is spending about 10x the money (light, system, ventilation).
