Set your light at 36" from the top of your soil. Lay your meter on the the soil with that fucking eye jigger pointing up, cap off on 100x.I’d like to test my lights man. I have some various Chinese blurple around. And that lux meter. How so?
Part of me in my head is thinking I could achieve better results with less light if they were say.... closer? Ie more intense? If the watts don’t matter and what the plant is taking in (the lux? Or PPFD?? Something....)
Know what I mean?
Get your reading. Multiply your reading by 100. Put it in on the hlg website calculator. That's your ppfd at 36". Check different distances.
Ppfd is just the range you want to keep your plants in so they don't burn or stretch. Think of it as ppm for light... same difference.
