But I agree. I looked at this as a hobbyist (no, not for weed) and thought it could be helpful since senors and hardware are currently as cheap as they are. But industrial agriculture has complete different set of problems.

Aside from that plants in general seem to be quite resilient and don't require perfectly balanced control loops. One might think so, but your room plants constantly dying is probably just due to not watering them for months.

So in the end having a few seeds and a bit of water probably beats the food truck full of tech on all levels of efficiency.

Still an interesting topic to create these environments. But perhaps not the correct approach to solve food shortages or help with problems large scale agriculture faces.
