Autoflowering light spectrum

Discussion in 'Lighting' started by Anzy, Sep 29, 2010.

  1. I'm about to start my first grow in a few years, and decided to try some auto blueberry with CFL's.
    Since i don't know much about autos and can't find too much information about them, i'm confused about which light spectrums to use and when? Do i go for 2700k from start to finish or 6500k for a few weeks then switch to 2700k? I've read that the best thing to do is use dual spectrum CFL's or use both through the entire grow, but the site was a little vague.

    Anybody have any suggestions?

    Thanks in advance. :)
  2. I usually see auto growers using 6500K for veg and switching to 2700K once the pistils start to show. Maybe leave a 6500K bulb in there during flowering for good measure.

  3. This.

    And yeah it doesnt hurt to have a mixed spectrum, (Of course, more 6500k during veg, 2700k as soon as you see pistils)
  4. Yeah except you dont go on a 12/12 schedule, obviously.
  5. Thanks for the replies guys, really helpful :)
