You want to get ppdf (photosynthetic photon flux density) and then use that to calculate DLI. I would shoot for at least 42 DLI. I shoot for 50. Much more than that is diminishing returns and increase risk of issues. IMHO, YMMV, etc.

Only peefect this apps pretty cool only other one they got is kelvin but I gotta pay 6$ for that is that even worth it ?

even worth it ?

IMHO no unless you have real questions about your lighting unit's color spectrum - and even then an overall K number won't help you much.

Photone app is pretty accurate according to Migro guy, as he tested it against his apogee. Apparently at around 800 PPFD, you want to add 3% to your readings if I recall. I have no complaints using it, my plants do fine. Just need to make sure that you use a diffuser. I did pay a couple extra $ for the LED full spectrum upgrade/reading feature. I can’t remember how different the readings were vs the stock reader. But it was cheap I think around $10? and I like the app so figured I’d support it.

Don’t have diffuser gotta go get matte white printer paper and tape around front camera

That’s what the app says

Yeah you just use a piece of standard, can't remember the weight, paper. 20 lb? 22 lb? Cut a strip and wrap it around the phone and tape it. You can slide it on and off your phone when you need it. That's how I do it at least. There's another guy on YT who made a diffuser with a small piece of PVC pipe and paper attached to it who says he gets more accurate readings vs the regular paper method. He tested it vs his Apogee as well.

I don't sweat my lights too much. I mean, I adjust the dimmer for various life stages, and once I start opening my canopy up and all that. And the app helps me. I "usually" have nice grows and I appreciate the app for that as it seems to help. Plus, I can tweak my height and brightness if I want to play with things like getting more stretch, see how far I can push them, etc. YMMV.
