Neps as epiphytes?

[Acro]

Do most Nep growers allow their plants to vine up onto things, or are they often cut back? I often see photos of plants that are only a foot in height or smaller. And none ever seem to be growing up anything.

This is a question that really depends upon the particular situation. Most of the time, it's a matter of preference or space. Many people growing in terrariums like to keep their plants shorter and bushier than those growing in greenhouses just to save room. Some people like to grow in hanging baskets and let the vines dangle over the side. Others will stake their plants when they start vining, and I've seen really impressive cultivated specimens of N. veitchii climbing up trees. Some species naturally don't vine very much and subsequently produce few upper pitchers (N. sibuyanensis and N. rajah come to mind). Also, when people want their plants to be mobile so they can bring them to expos and such, it's quite easier to carry around a plant without several feet of vines.
