Safelab - was Ventilate or Scrub

Thread thiefs got away with my thread. It is obvious to me that they
did not read any of the information at www.safelab.com.

From the little reading I've done it looks to me as though a single in
room scrubber will handle ALL of a darkroom's air quality control; and
that includes humidity. www.safelab.com appears to me to be a good
place to start for information.

If DIY is your thing I've no sites to recommened. Personaly I don't
need ventilation but could use a scrubber. Dust and humidity control
would be nice to have.

Scrubbers being of such simple construction should appeal to the
DIY set. Perhaps someone out there knows where there are ready made
plans and sources for materials. Dan

What humidity level would you aim for, Dan?

That's an interesting question. I'd like to hear other people's responses
as well. I personally like my darkroom to have pretty high humidity. Last
time I checked it was about 65%. I usually have a tempering tray running at
75 F so that naturally contributes to the humidity level.

Higher than normal humidity seems to keep the dust down to a minimum without
resorting to extra ordinary measures. I take my film (usually 4x5,
sometimes 120) out of the tank and hang it up on a "clothesline" in my
darkroom, no film dryer involved. In a couple of hours it is dry and dust
free.
