Faster or slower, my experience with a commercial mix with a percentage of
coir was that I could not adjust my watering enough to keep things alive. A
very, very strong "no" vote from me on the material unless your growing is
very well controlled, but why bother whn composted bark has all the good
things going for it as a component of a mix.

One very good reason for my bothering... I can't find a local source for
composted bark and it's so heavy that it will cost a fortune to ship.

If anyone knows of a Long Island source or if anyone is driving from Orchid
country to Long Island and is willing to bring some, please let me know :-)

Otherwise, I'm stuck either paying a fortune for composted bark or else
finding some alternative.

It depends on the state of the coco fiber. As loose (relatively speaking)
fiber of fine chunks, this material breaks down into a soggy wet mess in an
amazingly short period of time. When used as fairly coarse (or large
chunks) it does appear to last longer than fir bark. I wouldn't use coco
fiber in a terrestrial mix. Even the large chunk material holds a
tremendous amount of water which speeds the breakdown process. A similar
phenomenon occurs with cork bark. Large slabs of this material are
essentially indestructable and have been used for years for mounting
orchids. Someone got the bright idea many years ago to use granulated cork
bark as a substitute for fir bark in orchids. That material (the fine
grade) turns completely to mush in less than 6 months. Anyway, pine bark
mulch would be a better substitute in my opinion.
