I found it depends on your phone device...and not really that accurate... do you have anything to compare the app to an actual light meter??? Just curious as I have a Z fold 4 and it has 2 selfie cameras... each camera gives off different readings
Using vipsrspectra p2000.
From my understanding it is pretty accurate with the new iPhones. Not sure about other devices. There is a British guy that goes in depth about it on YouTube
You bring up a good point Jkash. Seems if you’re an ISO user, the readings are more accurate comparing to an android device. In my experience and usage on a iPhone 15, the app seems accurate enough for what I’m trying to accomplish. I definitely accept the fact that the app will not be as accurate as a specialized ppfd device but I also have no need to spend that kind of money on a tool like that.
Z fold 5 is android... samsung
I have been aiming at week 4 of flower for max strength on my lights and feed but I'm stretching that to week 6 this grow, I enter flower at 60% and bump them up 5% ish per week along with my feed. At week 6 weeks my lights will be at 100% and plants will be receiving their max food - week 8 then I start to back down the light and food.
