Everyday I read in forums and mailing-lists questions about this material to use as media, especially for Cymbidiums.
But it really helps to improve their growing? It's really miraculous as many people said?
I don't know exactely how it works but I have to impressions:
1) Is hard to maintain (it dry to fast in sommer) and probably there are the risk to suffocate the roots.
2) I think there are too much fertilizer (nitrogen) inside and probably in the long run this could be more dangerous than helpful.

Can someone help me to understand better?
Thanks
