16/8 is fine, but it seems most people like 18/6.

Just ordered a 150W Quantum Board, can I swap my Blurple UFO mid grow to the new board? Is it possible to increase flower size this late into a grow?
My Blurple apparently uses 230W actual draw but is advertised as 600W. If that 230W value is correct, does that suggest my new, much more expensive QB is not as good? Will it make a difference to the plants health? What are the benefits from the QB? Thanks!

Wow. Thank you so much for the reply. I have been playing with LUX meter app and my light. I was bit skeptical about the lumens that I would get from the 15W but as it turns out, it receives well enough ppfd. Still skeptical about the spectrum i am having.

Light schedule
So I got a new timer and messed up schedule. Plants got 16 hrs of light, turned lights out as soon as I noticed (5am). 11am-11pm light.(5 weeks into flower) Should I let plants have 12hrs dark now and resume 12-12 , or let lights come on at 11am(6hrs dark)

Standby lights in grow tent, under dark period/night time
My humidifier has a weak blue standby light. Does this make it impossible for me to use during the plants dark period?

Lightning question
Hey, Growers! This week I had to open together the two boxes, so now all the plants have both kind of lights. Do you think, it can have a negative effect on them, or maybe it's good at least for the 140cm height White Widow,because the bottom parts get some more light from there?

additional blurple lights
I also got the blurple lights from my friend. To keep the temperature down I haven't installed them yet and not sure if I will. Will they make a difference if I add them next to the current LED? If so should I wait until the flowering stage or anything like that?
