So i bought a cheap cob light off amazon and i plan to replace the stock COBs with some clu048 1212 gen6 90cri chips but im currently torn on what color temperature i should choose for them. Should i do i mix like 2700k and 4000k or just keep it simple with pure 3000k, Thanks

You can go from seed to flower with 3000k it has plenty of blue for veg...

I will say that the 4K vs the 3K I have produce a few % more umoles at the same drive current. Looking at the spectrum curves I'd just throw some 3500's in it and grow.
