I probably would have tried growing corn in pots even if most authorities hadn't said that it's a waste of time. However, their challenge made it imperative for me to try, and so far so good. True, the stalks are shorter than I would like and, true, I haven't yet harvested my crop, but it does look like there's going to be a crop. This is better than I did last year. It's even better than with some corn I tried growing just a few weeks before this batch. Well, we'll know in a few weeks because I will be posting a picture of the results. Hopefully, it will be a picture of decent sized ears of corn.
Some technical matters: variety-Mirai, number of pots- ten 5-gallon and one 15-gallon, growing medium- 1/3 garden soil, 1/3 vermiculite, 1/3 peat moss, location- coastal San Diego
