Oh, come on, lucky lucky you . I'm planning to have a journey in Colorado sooner or later; you know, it's not around the corner!!
Ok, returning to the main theme, for now I'd like to use these just for sprouting, but in the next future I'd like to build another system on my own for grow grasses. But maybe this deserves a different thread!

Sounds like you've already solved half the problem with stacked colanders. So, what's left? Pump on a timer with some tubing and a fine misting nozzle?
Direct hit! Some useful tips on this?
I came to the conclusion that what I need is (correct me if I am wrong):
- container for water (something like a bowl is just enough)
- a mini pump like this one. What do you think about it? Can i directly connect the pump to the power point/timer or do I need something else? The 12V power is pure gold and I have an old power supply for a PC: can I use it in some way to connect the pump to the mains?
- a timer to activate the pump every X hours. Are these kind of timer produced? I mean, I've only seen timer that activate at hour X every day, but never seen one that activates every X hours during day. Also, because the pump's flow is very low and the "Freshlife 3000 automatic sprouter" you posted use a permanent watering system, maybe I can also avoid to use a timer at all.
