Mini sprinkler for sprouts

[Jon]

Just adding some of these pics inline, so people can see what the pre-made commercial units look like.

Is your plan to use these just for sprouting, or also to grow grasses? (And I mean that in the perfectly legal sense, despite the fact that I am from Colorado ).

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?
