I spent years working with water baths and other stuff to stabilize
and control temperature. Then, I got fed up with all of it and
decided to experiment ... I only ever processed B&W film at home:
- standardized on two developers (HC-110 and XTOL). Then stuck with
XTOL.
- went to one-shot developer use at 1:1 dilution.
- allowed all chemistry to stabilize at room temp (72-76 degrees).
- adjust development time to suit according to the Kodak data sheets.
All of sudden, film development became absolutely consistent, I
dumped three cabinets full of unneeded temperature control junk, and
I could concentrate on photography more than processing.

I've just purchased the components to design and build some

I have the heating part down but am at a bit of a loss as to
what to use for cooling the different solutions.
Other than keeping the entire darkroom at 68 degrees or below
does anyone have any ideas as to how to keep developer, etc.
at the correct temp?
Unfortunately the tap water here runs 70-74 degrees at its
coldest in summer.
I'd actually like to be able to run at 65 degrees to keep
developement times long and controllable.
My only thought is a large container of water in the fridge
that could be circulated around the bottles and tank.
Any ideas welcome.
