I'm at 160 storage space right now and I haven't really had problems anymore. I keep everything at about 10 (10 corn, 10 carrots, etc). I only farm stuff if I need it or if it's a ton of time like lettuce. Right now I'm trying to get a little more maybe around 20 lettuce to make some salads. I don't really feel like grinding rn so I think salads are good for that but you still need to check a few hours later to make two more since they always want 4 salads.
