Online alarm clock for 2:25 am
Pause your overnight greenhouse checks in Otago and set the alarm for 2:25 am, so you know exactly when to break away from the current row and reassess the frost risk. The alert gives this stage of the job a clear stopping point, with another 35 minutes available before 3:00 am for anything that cannot be left halfway through.
Your greenhouse round may be quiet enough that headphones still seem connected even after you have put them aside. Check the alarm’s sound output before continuing, because its signal can be routed into those headphones without being obvious from the phone itself. Set a useful volume and run a brief test while you are still nearby. If the browser page stops running or the phone falls asleep, the greenhouse alarm may not sound, leaving you outside longer than planned.
Moving between warm growing spaces and the cold Otago night can make 2:25 am feel less predictable than the forecast suggests. If an air conditioner or circulation fan is running, place the phone where its alarm will not be masked by the steady noise. Keep it away from direct heat and condensation, and choose a spot you will pass when changing sections, rather than somewhere convenient only at the start of the check.
