It was a combination of the amount of ongoing daily work it takes to keep everything on-point and the fact that one bad accident can destroy an entire crop. Making dirt sucks, but after that, it doesn't take much to keep going (I probably average 30 mins/day on must-do stuff) , and it's much harder to kill everything at one time. And while I don't do it often, I *really* like being able to leave for a week and know that, barring something crazy happening with power or my water pumps, everything will be fine.
