PPFD measurement

Enter a PPFD reading (Photone, a PAR meter, or a phone reading in the Android app).

Free (Free and Pro)

Open in the app

Also called

PPFD · light reading · PAR · Photone · lux meter · µmol

Where it is

  1. “Tent” → “＋” → “PPFD measurement”
  2. or “Today” → “＋” → “PPFD measurement”

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

  • An external PAR meter/Photone or the GrowScope Android app

How to use it

  1. Open “PPFD measurement”.
  2. Enter the value in µmol/m²·s (or measure in the Android app).
  3. Save.

Result

The reading is in the light history and on Today; it drives light and CO₂ targets.

If you can’t see it

  • The browser itself can’t measure PPFD — you need a meter or the Android app.
