This is interesting, I got gifted an one of those hydroponic systems. The thing was 2 years old. Runs on a Raspberry Zero. The issue? SD card corrupt. I got an image from someone else and fixed it with that.

What's worse is that these things are connected to the internet (with VNC installed!), and they don't do updates...

The system is awesome, but I VERY quickly moved it to a separate VLAN.
