Lux Meter

[NoWorryLeaf]

Lux meters seems to be another option – I have downloaded an app on my phone to test it out.

Suggested

5000 – 7000 lux for Clone and Seedling

15000 – 50000 lux for Veg

45000 – 65000 for flowering

I’d grab an UT383BT from amazon or direct from Uni-T, mine was like $65 cad shipped.  There’s an app for it that pairs the sensor via bluetooth and lets you measure in calibrated PPFD/DLI instead of just raw lux, based on the spectrum of your light.  Its not a fancy & real PAR/ePAR meter but it will let you dial in your light if your girls move daily.

here’s a shot from the PPFD Meter app, I haven’t even tried the manufacturer’s iENV app yet.
