Light hours (18/6, 20/4, 12/12)

Also called

light hours · light schedule · how many hours of light · 18/6 · 20/4 · 12/12 · photoperiod · lamp timer

Where it is

1. Bottom menu → “Tent” → “Equipment” → “Light hours”
2. When entering PPFD — the “Light hours” field

The mobile and desktop versions are the same: the app runs at growscope.uk/app/ as a single column with a bottom menu of four tabs — “Today”, “Plants”, “Tent”, “Comparison”. Settings open from the avatar at the top right; the Archive opens from “Comparison”. On a computer the only difference is that features needing the phone’s camera, motion sensor or Bluetooth should be run from a phone.

Requirements

• A tent (on a balcony the sun sets the day length)

How to use it

1. Open “Equipment”.
2. Pick a schedule in the “Light hours” list.
3. The change applies immediately.

Result

DLI and recommendations are recalculated for the new schedule.

If you can’t see it

• To flip a photoperiod plant, the “Switch to flowering →” button on the plant card is easier — it offers 12/12 itself.

Direct link

https://growscope.uk/app/?open=equipment — Opens the app on this screen. A direct link opens the app straight on the right screen (after sign-in and encryption unlock). For features that need a plant you can append &plant=<id>; without it the current plant is used.
