I did on Friday.

@siLva_77, I was using a cheap LUX meter (BTMETER BT-881E) with a conversion factor of x.028, thanks to MIGRO. MIGRO compared the LUX meter to a Apogee Instruments PAR meter to get the conversion factor. The readings seem to be very similar, but the Lightray is much more convenient. In the app, you can choose PPFD, DLI, Lux, or Kelvin. Migro did a comparison, but used a iPhone 12 and a Samsung S22 (both outdated, IMHO). https://migrolight.com/blogs/grow-light-news/par-meter-apps-compared-for-accuracy?srsltid=AfmBOoqhp9mtT0dhcD3BpzIhk1kTIo_e7uXHk2X99Kd8Je5LDDY77flo I have not seen a recent accurate review of the Photone app with the Lightray Diffuser with the latest phones. Photone, of course, says it is within a few percentage points of pro PAR meters

Looking good there at the moment, I'm also growing blue dream but from seedsman under 300w so will be nice to see yield under a 600. Good luck and will pop back over to see how she's doing in flower.

@siLva_77, It doesn't seem to be. I'm only feeding 1.3 EC and it seems healthy and happy. Good luck!

@smokewizard, Thank you. You, too!
