I actually got the second portion of sprouts to work. I put them in the closet for a week, changing the water twice a day, and after a week they were finished. Very tasty, a more distinct taste of sprout, and not the taste of plastic one usually tastes when eating the version from shops. They were really good. BUt they were also extremely small, and gone in half an hour. I didn't put on another lot. I reserve my judgement a little while longer: Was it really worth the effort?
