For Vege : HM > HPS > CFL or am I wrong?

  1. I bought a HPS ballast and a 400w bulb. My plants are only 1-2 weeks old.

    I've read that HPS can do the job for the vegetative state, but I already got a bunch of daylight CFL's over my plants.

    Should I combine the HPS + CFL's to give the spectrum + lumens?

    Would that just be like pissing in the ocean?

    I dont want to waste electricity either.
  2. You can do either one. If you've got plenty of light from your CFL's(and you do at 1 week old) why change it? The benefits of dual-spectrum include shorter inter-nodal spacing. We want this so our end result is a shorter, bushier plant. If I were going for a few small plants, I'd veg under the CFL's until they were 8-10 inches tall, then move them to my 400W HPS. Your end result should be around 2 feet tall with some nice nuggets.
