3200k my personal or 5000k a mixture of both would be Ideal I don't know why you would want to only chose one though. This is all LED based I assume are you counting MH bulbs they can be very good for vegative growth just expensive to run.

Light for 4x4 tent?
Which would you go with for a 4x4 that is used for veg and flower: Mars Hydro TSW3000 or AC Infinity s44? I've got myself narrowed down to these two options.

Are there any recommendations for a light schedule for autoflowering?
I leave them at 24 hours. I start with the seedlings at 18000 Lux and increase it till the 4th week. After the 4th week I have all my lights at full power and the top buds have around 55.000 to 90.000 Lux.
