upvoted because you are trying a new technique. I really don't think it will work well, but we'll see in due time. you will probably get a few really small seed potatoes per pot though, and that in itself will be useful.

I did a raised bed potato system this year, but don't have enough soil to really fill the second level, so I wont get the max yield I'm looking for either, but every experience is a learning experience, and there is great value in that I think.
