Online alarm clock for 4:11 am
Waking at 04:11 gives you a quiet moment to get oriented before checking the greenhouses ahead of an Otago morning frost. You have not started the job yet, so use the alarm as the point when resting ends and preparation begins. There is enough space before 05:00 to get dressed, gather what you need and leave without turning the first minutes awake into a rush.
Because the greenhouse check depends on that early start, leave this page running after setting the alarm and keep the sound level high enough to hear. If you close the browser, the alarm cannot sound to send you out to the greenhouses; it also cannot wake a computer or phone that has gone to sleep. Check that the displayed alarm time is 04:11, then keep the page active until it rings. A separate phone alarm is a sensible backup if you expect to step away from the screen.
Getting to the greenhouses may take a different amount of time at 04:11 than it does later in the day, so work backwards from when you want to arrive. Allow for the full drive, the walk from your parking spot and a few minutes to collect equipment. Set out keys, warm layers and a torch before sleeping; that keeps the departure straightforward while it is still night and protects the travel time you allowed.
