pinecone as potting media

[naoki]

This is an abstract for a poster/oral presentation:
SHREDDED PINECONE AND PINEBARK AS GROWTH MEDIA FOR ORCHIDS, CATTLEYA SP.
, so we can't get the details. But it mentions that shredded pine cone or pine bark (instead of fir bark) did pretty well as a potting media for Cattleya. The study is done over a year, and it appears that pine bark were somewhat degraded by the end. So we don't know how well pine cone/bark will do over a bit longer time frame. I thought that some of you might want to experiment with this.
