The LEDs are great for small applications, but that's it for now. And I saw a few experiments where even the same brand had wildly different lumens between the same model of lights. They'll get there.

Yes, light cycle is important. You're basically fooling the plant into thinking it's fall, so time to fruit, with a shorter "day". I got skilled with this years ago when I was growing, ahem, something else. Back then I had two 1000 watt HP sodium lights. It was a rather large operation. Filled a whole bedroom wall to wall. Did all that 20 years to early.
