wow that is a hard one since we can't pause our plant and can't give password to ppl for chances of getting banned i recommend if you have a laptop take it and go to MacDonald a few day's until your plant's reach elder that what i did
Honestly there should be a way to suspend growth for long term absences, as real life sometimes has a way of creeping up on you. If it's a planned vacation, obviously you should refrain from planting close to that vacation.
There are times, however, where that just isn't feasible. A death in the family, for instance. You don't 'plan ahead' for something like that. Of course, if someone in my family died or became deathly ill, the last thing I'd be thinking about is my plants in the game, but it would be nice to have a way to suspend their growth or something, should something like that come up.
I heard of someone going away for a long time and when they got back their plants were just as they left them. As though they had been frozen in time (by KI?) I hope I heard right.
