    of my favorite temperatures!

    I'd try one or two or three or ... clip fans for starters.
    A small dehumidifier should be good for a degree or two
    or three or ... . Those degrees in Centigrade. Dan

    I just took my tap water temp 3 30 pm aug 6 the coldest possible was a steady 87+ degrees (F).....and that is with only a 104 degree outside temp.....almost an Artic Blast! In the winter it is not a problem....

    We've both a water supply problem, you're water is too
    hot, mine's too hard.

    My answer, Reduced Solution Volume, RSV, techniques.
    I process film, developer, fix, wash. I use very dilute least
    chemistry solutions. All are used one-shot. So, no
    stop. The wash is of the Ilford type; three
    rinses plus wetting agent.

    Same for prints; one-tray - one-shot. The single very
    dilute fix will give archival results with one fix and still yield
    great per unit of concentrate capacity. Diffusion washes
    are a BIG water saver.

    I work out of gallon jugs of distilled water. What's your
    room temperature? How about an air conditioner?

    Also single tank rotary with one-shot chemistry
    will use very little water though solution volume may
    be short of that needed for an archival single fix. Dan

    Dan that sounds very interesting,

    it could work for me....I can get my room temp to 78 degrees no problem and cooler if I had to, It just gets way more expensive when I try to maintain below 78 or so....

    i.e. one tray, delelope (extended times...?) 2. dump dev 3. pour fix in same tray/fis/dump 4. wash dump. 5 wash/dump 6 wash/ dump

    all with distilled water....

    what kind of dev times are you getting?

    I use a tub with ice to control the chemistry temp and I made a chiller for film wash using a 10 gallon bucket with copper tubing winding though the bucket which is filled with water and ice. Tap temp is 90 and 72 after cooling. 1 bag of ice will last for 8-10 mint which is long enough to wash film that has been treated by orbit bath.

    You've sheet film in mind? All in all work with the least solution
    volume which allows ease of processing. That may, with a little
    practice, be less than you expect.

    I've not tray processed sheet film for many years. One tray
    may do for one sheet at a time, but multiple sheets ... ?

    I shoot 120. I compound all my own chemistry. I am too
    little familiar with what you are working with to be
    specific.

    Essentially I'm suggesting the use of room temperature
    processing using the least amount of stored room temperature
    water. Your room is your chiller. Dan

    low tech chiller

    I'm a new guy planning a darkroom construction and I'm smiling here seeing that my plan is in no way original.

    Here is the sketch I just drew up:

    or one better, even. if you have a refigerator in your darkroom, buy a $5 roll of nylon 1/4" tubing, unroll about 4 feet off each end. Drill 2 small holes, grommet them (remember measure thrice, cut once) or find some existing grommeted holes, a simple pump, or alternately connect one end to water supply, other to a small tap near the sink....Voila! cold water, cheaply.

    Thanks, that is a couple of clever ideas
