Lighting color temp ?

3000k or 3500k, I wouldnt do 4000k unless it was 90cri and still might be hesitant. That light posted above looks like junk...

I am using 4k and i must say that it is a nice crisp white, 4k is in the middle between 2700 and 6500 should control stretch nicely.

I am now thinking again so is 3500k good for photoperiods too ?

I don't see why they shouldn't!
