Also pushing the XM-Ls at 2.1 forward amps yields a forward voltage of what appears to be 3.2 V on their 'electrical characteristics' graph. 30 x 3.2V = 96V, those drivers have a max of 95V, therefore it would seem 29 LEDs per string would be the max unless I'm missing something, with respect to Rives I think he was just estimating.

You'd have to maneuver your wiring for your string around so you don't just turn all the LEDs at one end of the panel as to not jack up your coverage.
When wiring the string one could just skip maybe every 5th LED then come back and get those with the end of the string. Those last LEDs would be the ones designated to be turned off with the switch.

i m certain you could run 30 XML diodes w/ that driver ~they basically run w/ what you hit them w/ you just want it to be within spec so they arent damaged or short lived
idk that i would put a lot of emphasis into dimming and shutting strings off unless it was a simple solution or you just really like to tinker

After a rocky start with some still-hot soil, my buddy is almost three weeks from sprouts emerging from soil. No signs of burn. Temps are cool and as you can see from the lack of stretch, they are loving the light. I'd estimate about 800FC, light panel is maybe 14" from canopy.
it took me a while to find a post where you said you used 1:1 WW to NW {which is what i thought anyway} i wouldnt be surprised if that is a blue-heavy lamp compared to what you "need." would you say it's problematic or 'freakish?'
more dense flowers does seem more desirable to me. I have a hard time imagining a situation where they are too dense outside of botrytis ~maybe an issue w/ certain strains?

What lighting schedule has your friend been using? Has he been gradually decreasing the hours, or just going straight from the veg schedule to 12/12? Keep track of how long it takes to see visible flowering - I've always been surprised at how quickly bud set takes place with LEDs.
So far 24/0. Flipped to a hard 12/12 and turned on the WW afterburners for flower.
Other than a little burn from not-quite-fully-composted soil when the seeds were first planted, they have done pretty well. Nice bushes, nice color.
I will be helping him sex the plants, as this is his first ever grow. Then he'll transplant the females to 15 gallon geopots.

24 to 12 is how i have always done it; i think about working fancy schedules and i have done the 'short night' thing like 18/6 for veg and dont see much if any difference but it seems a bit like work and taking the simplicity out of a working scenario
those are look'n good ~exciting to see them flower/find out sex/check out the light
