I'd also reconsider not
making it automated. It's not that much for a controller and
if you have a place to mount it and can work it in, having it
fully automated sure makes it a lot easier. How many times
are you going to turn it on, forget about it and have it run
for 3 hours?

A midway option is a mechanical wind-up timer such as I installed on a
hose bib for the g.f.'s flower bed. Turn it on for 20 minutes or 2 hrs
as needed and it turns itself off. No batteries to wear out, no AC to
run, no controller to program, and no worries about forgetting to turn
it off, or not being home to turn it off.
