TX will have a look.
I will buy a small farm this year (if I'm lucky) and I do believe your general approach is very interesting.
Let see how it continues.
Regarding sprinkler etc. I saw a bigger drown spraying stuff. If the autonomy is very reliable you could refill it regularly.
Sprinkler I'm really not convinced but we don't have a lot of sprinklers in field in Germany.
Might be a little bit waist full from a water perspective
