Haven't finished a cycle yet so can't really say. First time with autos, 9/3 light cycle, run in room and first time with LEDs. Still waiting on my ppfd meter to really dial in the settings at different hang heights. It appears 18- 22" is best for max coverage, this hasn't been confirmed by me yet though. Very easy setup and nice sleek design. I wanna say it was advertised as daisy chain, although I think only the dimming function performs with the daisy chain. (Still need 3 outlets for 3 lights, as opposed to 1 outlet for 3 lights) At least that's my understanding so far.
