I have grown Plectrophora triquetra since 1995. I have several clones and all of them are grown mounted. They are currently on pieces of fir bark, but I have also grown them on cork. For many years they grew with a minimum of 52F nights, for the last few years with 54F minimum. Daytime maximum of 80F, usually in the mid 70's. If I had a warmer greenhouse, I would try them there, perhaps 56-58 minimum night. With good humidity, I find they do best when allowed to approach dryness between waterings. For most of the year they are watered every morning with enough air movement that they are just dry by morning. In the winter, when humidity stays high in the greenhouse, it may be several days between waterings. Other plants growing close by that do well are many Sigmatostalix species, Dend. pentapterum, some Aerangis species,
When I have had issues with water quality, they have definitely gone down hill. They were certainly damaged by sodium in the water supply, but also showed ill effects from pure water with a low pH. I saw this species growing in northern Peru a few years ago. I would describe the climate as intermediate, the days were warm, but the nights cooled off. They were growing on the trunks of large trees near a coffee finca that was near a stream, but the trunks were not mossy. There were mature plants and lots of seedlings, they were growing in filtered shade 6 to 8 feet above the ground, Marni -- Marni Turkel Stony Point Ceramic Design 2080 Llano Rd 1B Santa Rosa, CA 95407 Phone 707-579-5567 Fax 707-579-1116 Web http://www.marniturkel.com Barrel Rims: web http://www.BarrelRims.com _______________________________________________ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
