Mine actually started out in regular potting mix with coarse perlite added to open/drain better. That was a disaster, or at least I blamed my dead/dying plants on the media. Late summer I mixed 1/2 Douglas fir bark orchid media (medium) with that potting mix and repotted every single plant. So far the plants have done much better with that 50/50 mix. I do fertilize every week or so with 1/4-1/2 dilution of orchid fertilizer. The same thing happened with my vanilla orchids too, and they were all re-potted with that same 50/50 mix. Again, the same result. Lots of nice, vigorous growth. I will have to decide whether I want to re-stock those Sarcoglottis and planiflora plants this spring. I simply can't grow EVERYTHING I want, particularly when I am purchasing 98 seedlings of each variety/species at one time. I have 196 seedlings coming in on Friday! They are fiddle leaf ficus and staghorn fern seedlings.
