So, the grain soaked under water to reconstitute it for about 8 hours. Then I strained off the water, put it back in the same bowl, covered the bowl with a wet towel and a sheet of plastic wrap, and let it sprout. I do rinse the grain once or twice so it doesn't dry out. (Fill the bowl with water and strain it again.)
I'm pretty happy with the looks of this. I've had grain that didn't sprout at all. I don't know if it was exposed to some anti-sprouting chemical or radiation? So far so good.
