When you found you setup - theres a company in Germany where you can order custom designed led boards with whatever you want on it. Whatever...my light is experimental. i don't recommend building one just like it. i did this to help me understand beam spread, overlap, and the influences of power and spectrum.
i can make the light perfectly even all the way across on the next one from what i've learned using this one.
i'm living in a drafty old farmhouse right now while i build a home. when i get into the new house i'll build a more refined one. or 10.
oh no,snipp, i think i see an underdeveloped trichome! but i'd smoke it anyway!

50" = 127cmThis is a not so bad idea at all. .
Good to see we get on a adult discussion level.
Lol - exactly…. But If you can sniff it another way I’d pay to see that - off topic but heroes on topic so perhaps not too bad…. Normally those games of Pong began with a couple hits Sid too; case a beer each would barely phase us then & back then, crazy… late teensSniff like through your nose?
I have done this once as a 17y old teenager. 3 or 4 shots tequila over 2 hours kept 4 of us wasted. Next day was very bad with a lot of nose bleeding.

…. I’ve built maybe 30-40 lights in my day; here’s one I’ve still got pic of and in use 640w IIRC

I’ve even built LED with HID in one fixture but disassembled years ago as it was far too bulky and dated tech
Many ways to skin a cat; time and place for both LED & HID, they work great together, especially HPS & LED
HPS is tons of cheap far red & IR, no better way to get it and you’re crazy if you think your plants don’t benefit from it…
Peace y’all
If you go to bloomtech, which is a cannabis lighting manufacturer and growshop, there you will see almost 100 such ppfd plots. That guy designed a measuring area with variable walls and a green floor, as to resemble a plant canopy. Later took his readings to calculate the average PPF & PPE from these PPFD plots.actually ca++, i have plotted entire 5x5's and 4x4's and averaged them to get readings to verify.
i have stated spot center readings here and then posted what the edges are getting.
but if you like i will do a little measuring project.
i have a net installed over my plants right now.
the plants have not reached it yet so it is free and clear of all obstacles.
i will plot every fucking square on it for you and report the readings. the light goes off at 2:30 my time so i have enough time right now to do it.
i'll be back!
You said umol didn't exist at the lamp, lumens do. Then went on to sayi did not say you couldn't calculate ppfd knowing power and area. i'm saying that for practical daily use a meter at the target is perhaps easier.
i normally run it with the skirt on which radically changes the readings.
i need to remove some of the center bulbs on this one.
what the readings show is that dead center you have the greatest beam overlap so this area could be "thinned".
when i get in my new spot i intend to illuminate an entire room at this level.
you cannot project a lumen rating onto a square meter and get ppfd. you must actually read the light at the canopy to get ppfd. you must use a par meter to do this.
