Autoflowers & CFLs

Discussion in 'Growing Marijuana Indoors' started by ihavethajuice, Sep 15, 2009.

  1. When growing with autoflowers, does it matter how much lumens during flowering? Or can you use either 6500k or 2700k?
  2. You need to understand what lumens are and what kelvins are. The 6500 and 2700 are NOT lumens, they are kelvin rating.

    Since your question was asking two different things I'll give you two answers in hopes of helping you out.

    Autoflowers like just as much light as a normal MJ plant. So, during flower if you can give her 10k lumens, she'll be a fat and happy girl. That is, 10k lumens, at the canopy, per plant.

    The kelvin rating (which is the 6500/2700) is the temperature or more specifically the "color" of the light. One is a very bright, blue, and cool looking light. This is the same as a metal halide, and perfect for vegging. The other, is the warm, softer, yellow/red looking light that is similar to an HPS and is prefered for flowering.

    Now, with that said, you want to make sure that you are using the warmer, yellow lights for flowering. You can use the blue lights, but you won't get the same results as you would from the yellow lights.

    I hope this answers your question. Just remember that the CFL 6500 and 2700 doesn't have anything to do with lumens.

    DO WORK said it like a pro. Lots of Light The more CFL's You get in there the better off you will be. Just remember your Temps and You need that Fresh Air too.
