  1. im going to start a pc grow box in a week or two but i want to double and triple check everything because i am new at this. I was wondering how i could cover up the light that comes in from where the fans are?
  2. Duct tape on both sides of the hole should solve the problem
  3. If you duct taped both sides of the hole the fan wouldnt work... or am I misunderstanding what ur tryin to say?

    My friend I think you need to build a light trap....

  4. Use multiple bends to create a "light trap", sort of like the S-Bend piping under your sink.


    Spray the interior with black matt spray paint.
  5. thank you to both midwestpothead and joe luxen exactly what i needed!

  6. Woops Yeah you are right. I didn't think before i wrote. I just assumed he was covering holes that were in the case.
  7. youre thinking to hard,

    cardboard and ductape.
    just make a flap so when the fan is on it will be out of the way,
    but when its off the hole will be covered.
  8. Yea...Duc tape, or reflective tape is easy and cheap....
  9. Rumpleforskin has an awesome tutorial on how to build light trap mounts for pc fans, him.
