Explain it in your own words. That's how you'll remember it.
Agreed. Sometimes it takes seeing it from another perspective to see the lightbulb go off

So... this lux meter is working good. Trying to find a conversion factor... not so good. HLG 100.
Anyhow, looking at the ppfd measurements and what they are at what distances, the lux x100 number seems close to what the ppfd is lol. There's a YouTube video of ppfd testing this light, my lux readings at those heights match the ppfd readings in the video pretty close. So... WTF lol.
Look at the lux to ppfd conversion link i posted several times...
The conver factor depends on the diode(s) not the board...
I assume that’s either a v1 or v2 diode...

I did that but I must be doing something wrong.
Gives me 1.73 as the result. Is that my conversion factor? That might make more sense.
Samsung diodes.
Lay out your steps...
Nah that can't be right either lol.
What? You did steps right..
Board at the top of the tent, almost 4 ft gets me 100 x100. Plugged in it gives me 143ppfd. I can't get it any higher. Just doesn't seem right to me.
Why not seem rigjt? Too dim, too bright?
These are supposed to be smaller/cheaper boards I thought?
The guy in the video had 100ppfd at 36". I get that on my meter. 18", he had almost 300, same as what I get.
Using the formula, boards 4ft above the meter and I'm getting 143ppfd? Why the hell doesn't everyone buy these boards then lol.
Too many people got burned on cheap blurples so everyone and their moms a LED skeptic. Or they’re stuck in their ways with HPS.

Well, where I would ordinarily put seedlings under the HPS is reading real close to 100... sonofabitch lol.
I don't know how much the conversion factor changes that. I do have 2 in there, so it just must be that bright.
Unless they are dried out or beyond your trich color threshold, keep flushing, only improves tastability.
if you need it now, really doesn’t matter, you harvest...

btw...told you that meter would be useful...especially for a guy like you...take it outside...
