That sounds like a serious farm. I thought my 1 dog and 20x40ft garden was a lot.
The automation should be a fun project. I know I at least have to get the side roll up motors going or it will bake out at crazy high temperature in the spring. It already hits 90 on a sunny winter day.
There isn’t a whole lot of info on the roll up motors. I think they are mostly used in China, but I know I have to then supply my own relay, power supply, controls, timers. That’s where the raspberry pi starts to look good as a central controller for everything, plus expansion.
