Sure, I got sweet potatoes from the store that would fit in mason jars. Cut in half, put tooth picks in to hold them at the top of the jar, with 1/2 to 1/3 above the top of the jar. Filled with water and sit in a sunny window. When the slips are over 6 ins tall, wiggle them off and place in a separate jar of water. I like 2 if not 3 sets of leaves. Then I set them in dirt in tires or buckets ( big planters). Sweet potatoes like a little stress so not a lot of food in the soil.
They like it kinda poor, they like a little stress. Oh, put the cut side down in the water. I live in MD, so I wait until Mother's Day to set them out. I'll show you when I do. Set slips with roots attached in the water. They will be fine if you keep the water level up. Hope this isn't too confusing. I don't explain things well. 😏
