i have received wonderful reviews from people both pro and con. i finally heard from some one in costa rica who told me that coconut husks (with coconut carved out), and coconut coir (ground down) is used for orchids successfully if not over watered. i am going to take everybody's advise. i am not going to plant any new plants until i see some success from the few i have already put in coconut coir. i will report back later.
