3200k for 12/12
5600k for 18/6 OR 20/4 OR 24/24..what ever you decide.

Personally I prefer 18/6(on/off) to begin with for VEG
And then go to .....12/12(on/off) for FLOWER
Read up on the strain you choose... all strains are different so there may be different needs or wants from the strain you choose for humidity.
Oh and you normally want high humidity to begin with once your seed has sprouted and then lower once you are later into veg/flower. But I really don't know how much of a difference humidity being low would make later in the grow...? anyone have any ideas about that? Maybe someone can confirm.
