How to use the online alarm clock
While preparing to shut the greenhouse before the evening chill, set an alarm for 5:13 pm so the job is not lost among late-afternoon chores. That leaves a useful marker before 6:00 pm, when cooler air may already be settling around the garden. You can gather the latch key, check the vents and leave anything needed by the door beforehand.
Greenhouse work can involve rattling panes, running water or nearby garden machinery, so choose a signal you can hear over that background noise. Raise the alarm volume, then test it from the spot where you expect to be working rather than beside the phone. Keep the browser available and the device awake: if either stops running, the alarm may not sound and the greenhouse could remain open as the temperature falls.
Before heading out at 5:13 pm, notice whether the afternoon air feels damp and check for condensation forming inside the glazing. Closing every vent while warm, moist air is trapped can leave the interior clammy overnight. If conditions allow, give the space a brief final airing, then close the vents and door securely before the colder evening air takes hold.
Common questions
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 5:13 pm?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
