Here’s my room with 12 of them and 2 6 bar fixtures, which aren’t nearly as good imo lol.
Right on! Wow .. that's quite the setup there! You got more light than Jesus look forward to insane buddage. My space is only 2x7 and I only have only 2. You must be running them dimmed down quite a bit? I was definitely getting more canopy penetration with them dimmed down...

I still don't know what is the best for when plants are done stretching? I've had mine 10-20 inches full blast, although now I dimmed to about 80 @ 12 inches. Not seeing any sign of light burn, although they did curl up a bit when temps got to 31C. Seeing a slight hint of wanting to foxtail too... White hairs very ripe at day 47 of 55.

No complaints though! I still got 19 days left on my gorilla girl and I'm gonna blast them one more time before flush with 2.0 EC

Have 4 fixtures with 3 fotops each running about 570 watts per fixture. I might have to dim them some but so far everything seems fine. Hoping for a good yield but we will see.

I hit mine with 800-1200ppfd depending on the height. I wouldn't trust a conversion. Try getting the hydrofarm par meter it works as well as the others from my testing. Last I checked it's only $100
How do you get ppfd reading from the hydro farm par meter does it have a function for it or is there a conversion from par that you use?
