My wife used to do them all the time. She really liked the alfalfa and mung bean sprouts. Both are really easy to do and only take a few days from start to finish.
We've eaten the sprouts and they were really tasty. Do some investigating though. We stopped growing them because I heard a blip about some potential for bacterial growth. Never had the time to investigate it any farther. If I recall right, it was only one or two types of sprouts that there was a potential problem with. Kinda miss those fresh sprouts this time of year.
My wife use to work for a guy who was setup for production growing sprouts and mungbean. He had a big building and this tray system set up like a hydroponics deal. He could turn over hundreds of trays in 3 days if i remember right. It was 20 years ago though so i dont remeber his complete setup. I only saw it once for a brief few moments. He sold them to local stores.
