Anyone have a meter to measure the light intensity set by the dial?
I turned the dial up from half way to full blast. Using the ppf phone app it only increases 50. (From 500-550). I don't think the actual number is accurate but figured I could use it to base intensity differences. Just curious if the phones not picking up the increase. Or if that's really the range on the dial. (Pics just something to look at)

Well... I've got it dialed in a bit better and consistent... still hitting night temps of 64 but heater on the way. These photos are 6 days apart. I'd say the lights doing pretty well. Updayday is hanging at 23" obove canopy, Turned up to 100% power. Will leave it like this and let plants grow into light until something tells me to raise it.
day temps 82. Leaf temps 80. RH 40-50%

Photone app works quite well on my old iPhone 7. I was surprised. Found it extremely helpful setting lights.
Photone really depends upon the phone hardware and which version of that hardware. Lots of users have claimed it's pretty bad on most Samsung phones. I know that BK ran it on his Iphone 13 and it wasn't great by running mine side-by side on my iPhone XS Max and my Phantom Photobio showed that with my phone the readings were surprisingly pretty damn close, within 10% or less difference.


iPhone XS Max (wrapped diffuser) vs. Phantom:

Photone: 1198 Phantom: 1122 Photone: +7%
Photone: 750 Phantom: 735 Photone: +2%
Photone: 672 Phantom: 644 Photone: +4%
Photone: 573 Phantom: 530 Photone: +8%

What distance are you from the plants? I’m a little over 30” on full power. Just transferred to 3 gal pots a few days ago.

I ordered 5g fabric but they sent me 7 I do believe... was trying to transplant into 5 lol oh well... I have mine 33 in at 100% .. going to move some into 5x5 soon, and carry some through bloom in here. I want to test the full cycle of the light.
