>> I travel quite a bit. Who was going to tell me whether the plants looked healthy? Certainly not my children.

Why not? Why do you keep your family members away from your fantastic project? I would have loved to see something like "my younger kid noticed the leaf ...", "My wife watered the plants ..." etc.

Please remove all tech stuff from your garden. Manage it as a simple human. Let other humans of your family also take part in it.

While your project is technically awesome, you have removed all human factor from it, including yourself. You are letting the AI agents invade the last remaining turfs of the human tribes - the garden work.

You don't need a perfect, highly instrumented garden. That was never the need. Imprecision, lack of full metrics etc are perfectly natural. That's not achievement. That's vulgarity of pouring tons of tech into something natural as a garden, just because you can.
