Easy way to grow some potatoes...using those old Amazon boxes. Great for on a patio, etc. (Tho, if I had it on the patio, I'd probably give a shot of spray paint to the outside so it doesn't look like a cardboard box lol) He used a 12"X22" box, and got around a 5-10# bags worth. Good way to recycle and get some great food too!
