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.
