I had one years ago. Would like to start growing a variety of sprouts once again. Is there a better way of growing sprouts other than using a small commercial plastic container. After reading many comments on various sites, it seems they all have a tendency to clog. Are too small and also too short. Have read suggestions about using Bell jars and cheese cloth. Can they be grown in flat trays , in dirt, outside? Please help. If there's a place for info on this....it's here. Thanks!!!
