Northiana better grown in a big or small pot?

[edwardyeeks]

Just wondering, is it better to grow a northiana in a small pot or a big and deep pot? Since it's natural habitat is limestone cliffs, I assume that it needs a wide surface area to grow naturally. My media will be consisting of charcoal, limestone, perlite and perhaps some coral stones. But is it better to grow northiana in a bigger pot? When I had a northiana before, I grew it in a pot around 8 inches in diameter and nearly 8 inches deep. My northiana grew beautifully, (although it died out of hot weather). Now I am getting one, so please give advices and opinion on the size of the pot, thanks.
