Where it is
- Bottom menu → “Tent” → “🔬 GrowScope Lab” button → “Light Sweep”
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
- Phone camera and a white card
- Saving the manual mode — Pro
How to use it
- Take an anchor reading with a meter.
- Walk the canopy points with the card.
- Compare with the map.
Result
Per-point deviation of real light from the model.
If you can’t see it
- No camera — open on a phone.
