Here is something that I ran across at The Orchid Source forum. It seemed so important to me that I compiled all the different comments by Mitcholito into this document with some of his images. What this young man has done is simply outstanding. He has even had orchid seeds to germinate and grow on these moss covered terra cotta pipes! A real feat and something worth checking into. Hope you all enjoy this. Will update once he posts new info. Cheers.
