I'm not sure if this question belongs here or in "General Orchid Culture", but I've read many growers both commercial and hobbiest are using coconut husk chips. I'd like to know other people's take on this material. I live in SE Michigan and am having a problem finding a local vendor for these chips...they aren't especially expensive but once you add heafty shipping costs, they become a pricey item. Thanks for any advise....
