Munster works well, as does mild brick, and I use low sodium Farmer cheese. My pablano's can get as long as 4 inches and are wider then anaheims, I've seen imported ones in the grocery that are even larger. I'd guess down there you should be able to grow them quite large. I use tomato cages on them to keep them upright, otherwise they wind blows them over and the stems sometimes break. I do the same with the anaheims. Here's some pictures from two years ago. Mine are only about a foot high right now. Well, they may be larger, I've had the flew for a few days and haven't been out there for a while. Not the best picture, but you get the idea.
some pablano's from that year.
