    hi im a noob too lol

    but as far as ive been reading, the warm 2500k CFL's should be used for flowering. white or "natural" 5000-6500k CFL's should be used for vegetating

    thanks ,
    but thats not what im asking ,
    i know about the different color temps 2700k for flower and 5000k or higher for veg ,
    But i wanted to know if theres a difference between soft light and warm light ?

    The correct terminology is 'cool' and 'warm' cool=6500k warm=2700k

    cant say I have come across soft, sound like lighting designed for wining and dining the missus not growing bud!

    Soft White (3500k)
    Cool White (4100K)

    a quick google search came up with this.

    its just that all the stores around here sell only 'cool white' or 'soft white'
    no warm white
    so i was wondering if soft white and warm white are the same ,
    the soft whites i get are 2700k
    im thinking its just the way they label them

    I just bought a few "soft white" bulbs. The 42w ones are 2700k, as it says it on the base of the bulb. The 23w ones dont say anything about the spectrum but emit a much more bluish light. Yet both bulbs are "soft white". I cant figure it out. All I know is I have a bunch of 23w that I will use for veg and then click on the 42w 2700k when it comes time to flower. I am almost done building my setup, I will post pics when done.
