I sprout any old seeds and beans from the health food shop. They never look like the ones you buy in the supermarket, because they've been grown in the dark and also flattened to give a uniform shape.
BYW, I've been warned against using seeds meant for sowing in the ground because they may have chemicals added to them, fungicides, that kind of thing?
