I had successful rooting in my Aerogarden. I just placed the cutting into the aerogarden plug, and waited. My problem was that the plant seemed stunted, and wasn't growing very fast. In fact, my seedings outpaced the cutting within a few weeks.
Awesome! There's a few that I think would work great. Have you guys thought about having it narrowed down to a few? For example, people could compete with Brazilian Starfish, Yellow Brain Strain, and Aji Fantasy. Maybe that would get complicated.
From what I've been told, they are a close relative of the Tomatillo. I grew ground cherries this year, and wasn't a huge fan. Some people really love them though.
