I bought 3 plants on a trip to Kanchanaburi 6 years ago. A small nursery was about to sell the rest of their stock of orchids. The plants are in their pots since then, hanging less than a meter from the shade, like epiphytes. They have been blooming more than once a year. The 2 pots on the photo have a lot of seedlings growing around the pots. I did not do anything for it. I will repot soon, keeping the adult plants together and removing the seedlings.
