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.

Temperature VS More Light which is better for buds size and potency
Should I continue to use two LEDS if temps are reaching 87f during flower (day 1) or just move plants more towards center of tent and use one LED for better temperatures (75f) (only growing two plants). lights are 1000w bestiva and are in a tent that is 24"x48"60".

Currently my lights are on a 18/6 schedule, from 6am, until 12am. I want to change their light cycle to start at 4pm and turn off at 10am, so the heat of the light balances the chill of the night. Whats the best way to do this, without triggering flowering, or stressing them.

Is this light good enough?
Will this be enough for 2 auto flower plants in a grow tent? Or will it work for one? The tent is 20x35x64. Or should I get another one or a different light altogether? Thanks!!

Less light for an auto? Maybe 12/12?
Been going with 18/6 for my cream autoflower from growers choice from Day 1. Now 5 weeks into flower I’m wondering if she would benefit from less light, like 12/12, as you would for a photo period plant. What do you think? Would she be happy flowering in some more dark period?
