hey bro, don't take this the wrong way but, if your posts are going unanswered
it's probably because your questions have already been asked and answered
more times than i have hairs left.
here's a link to a thread that will answer all your questions regarding a DIY
rubbermaid build.
DIY stealth Rubbermaid growbox
the fact is my friend, we're all alone in this together. what i mean is, we
have each other to teach and learn from but, ultimately, we have to be able
to stand alone and find the easy answers ourselves so, when we have
hard questions, people don't act like we're the boy who cried wolf.
try clicking on the button up top that says '
HOME', that'll take you to the
homepage where you will find links to all the forums, then, if you click on
each of the forum links it will take you to the main page for that particular
forum and there you will find all the sticky's, you should start by reading
those.
anyway, what brand of pc fan you use makes no difference other than some
might be marginally quieter than another.
if there is a grow shop in your area they will probably carry 'axial' fans which
are what pc fans actually are and they will have them in more than 1
size, plus they run on regular household current so no 12volt adapters
are needed. they're a bit pricey though which is why so many people on
a budget opt to salvage an old pc fan or 2 rather then buying one.
good luck with your grow, if you're persistent, you
will succeed!
