If the pot's big enough, it'll be fine. If its too small, you'll usually just end up with a smaller crop. Carolina Reapers are pretty small peppers, and we got a pretty good yield last year, but when I went to yank the dead one out (has a very woody stem to it) to prep the pot this year, the root ball took up the entire pot. I'd have never known they'd do so much better in a bigger pot, but there was nothing wrong with those.
