Yes, just the stockings, Tolumnia and Dockrillia don't like to be too moist, both mainly get their moisture from the atmosphere, the Doc is usually found near waterfalls and gets light overspray occasionally.

Other plants, such as yours may be different, but if you have a look at these plants in the wild, they just cling to the tree trunks and don't have piles of moss to sit on. There may be a slight build up of debris over time, but not a lot.

Growers tend to forget how these plants grow in their native habitats and don't research it much. I personally try to find out what they look like in the wild, and there are plenty of Websites showing them in situ, then try and reproduce those conditions as closely as I can.

Aesthetically orchids mounted with moss look good, but, is it faithfully reproducing how they would be in the wild ???

I am not saying that it is not right to use sphag, but try some research and see how a particular species does survive in it's natural state, I think a lot of people would be surprised.

This was only pointed out to me recently by a long time breeder of orchids, and he has changed my way of thinking with mounting orchids. Sometimes the moss provides too much moisture and they in fact, only need a spraying twice a day, such as my Tolumnia.
