Hey guys I need some tips!

  1. I have a 400w HPS light (open air)
    Small HTG grow tent
    6 inch 424 exhaust fan vented into the attic.
    This setup is contained inside my closet

    My temperatures are staying up around 90 degrees when ever my light is on. When the light is off it sits at exactly 76 degrees.

    My closet is also always at 76 degrees no matter if the light is on or off. So I know that its not recirculating hot air back into my closet.

    As of now I am thinking my only options are:

    A: Get an air cooled reflector
    B: Get a smaller bulb and ballast (250w)
    C: Both

    I would hope that an air cooled reflector would be enough to get me down about 10 degrees. because I would love to give my babies 400w of light to let them plump up to the max.


    Thanks for any help you may have!
  2. I'd go with A. 400w > 250w.
  3. I have a Air Cooled 400w HPS. Works great. Ducting mates up with both ends so air flows right through it easily. In my 32x32x62 grow tent never gets above 80.

  4. Bumpities!!!
    Does anybody know exactly how much heat will come out of a cooltube with 400w HPS inside?
