I had those lids on a gift list. My family never knows what to get me, so I have to give ideas. They work with the wide mouth jars. So far so good. I may order more, the shipping is more then the lids though. I may need to find another source. http://www.amazon.com/Sprout-Ease-E...F8&qid=1388414891&sr=8-1&keywords=sprout+lids I have never sprouted on the large scale like you guys or tried wheat yet. I did sprout in smaller mason jars that I had on hand. I sprouted BOSS, oats and a mixture of beans. The bean mixture got smelly and I threw it away, the oats took awhile but the girls loved them. The best was the BOSS and they really loved them and they sprouted pretty fast. It was really hard draining and rinsing the regular mason jars especially since I used my hand to drain them. These new ones are really simple to use so far. I am trying lentils right now and since they are the seeds for human consumption, I can sample them too.
