    Hi, newbie with some questions. thanks in advance for your help.
    are ventilated lights a gimmick or are they the real deal. do they make a big difference? is there much of a difference between the different kinds of rectangular reflectors? any superior models?
    anyone know of a way to build-your-own carbon filters that is cheap n' easy rather than spend big bucks on the premade ones?

    Hi, another newbie haha. Well i got a light question. Would it be necessary to use a ballast on a 400W HPS???? This is probably a dumb question but just wondering. Any help would be appreciated. Thank you.
