http://sproutpeople.com rocks for info on how to sprout various grains and legumes and other stuff.
I used to do it a lot--have done a wide array of gf grains--rice, millet, buckwheat, oat groats (I think that's what they are called b/4 rolled???), quinoa, along w/ legumes--both chickpeas and kidney beans. W/ grains, you can dehydrate them after sprouting on a cookie sheet in the oven then store them in a jar in the fridge for later use (they'll last a long time) and then either grind for flour to bake w/ or just cook up (like w/ rice). The legumes I would cook right after sprouting (until soft/done) then freeze for later use. I loved making bean cakes and cookies out of the beans, or sprouted chili.
I don't do it much now (I'm grain free and our family doesn't eat many grains anymore) but found it pretty simple and not time consuming. I used a mason jar w/ a peice of mesh from a screen from *something* (can't remember what) that I just cut into a circular shape. Made a couple of these and used the jar lid w/ the hole in it--worked fine.
HTH!
