Cooltube vs. Sealed Hood ??

Discussion in 'Growing Marijuana Indoors' started by newgrowNY, Feb 7, 2009.

  1. Is a Cooltube just as effective as a more expensive sealed reflector?

    Do you get a better light footprint using a hood, or is cool tube w/ wings just as good?
  2. I'm no physicist, but to me it seems like a cooltube would be a bit more efficient for cooling than a sealed hood. Just because there's less places for the air to go - it has to shoot straight through. Same thought applies to using straight ducting instead of the 'accordian' style (I don't know the terms for these things).

    For the light footprint, I don't know.
