Mod: growthManager
Neither can I, Google Translate does wonders ;) It basically takes over and supersedes the built-in growth script. It allows you to shift all fruit growth that would have otherwise occurred during the day to midnight (though that can be problematic if using multiple fertilizing stages) or to keep the default setting, but control plant growth, so you don't end up with fields that are in-between growth stages. It also allows you to control growth stage duration (i.e. you can fine tune them, to make them longer or shorter).
