@SoCal gunner , what is your set-up again, and how is it working?
I'm running a good sized evaporative humidifier wired to a digital controller in my roughly 160 cuft "step in". It holds about 5-6 gallons of DI water. In a desert climate I don't think I would want it to hold any less to avoid the stress of it running empty.
