I repotted three Encyclias today that were all new acquisitions and all suffering from some degree of root rot. Since they were in plastic pots with bark mixes I decided to try repotting into clay pots with an aggregate, more specifically a material called Pearl Rock. It looks like whitish river rock basically. I'm not sure if I can mention the manfacturer here but if anyone would like specs I can message. Anyhow, my inquiry is for some ideas from anyone experienced with Pearl Rock, river rock, or something similar with orchids requiring drier culture? This is partial experimentation but I'd still like to hear any suggestions, comments, kudos, RE this product or anything similar. Also would love to hear of medias you've had luck with specifically for drier culture orchids like Encyclias, etc. By the way, the species being repotted include two E. profusas and one E. cordigera 'Chocolate'. They are in a western window upstairs but I'm considering moving them outside into higher humidity for the summer.
