They slowed down drinking a bit, for now.
2/4
I put the new light in yday, tarantula borg v3.
I don't have the controller yet, but I did my best to set it to spectrum #49. Resulted in 11-1400 PPFD across the lower and higher canopy. The plants loved the first day.
I got the controller, set it to 59% power spectrum 49 which lands me at 640w. The same wattage as the previous light, much more photons.
