I've been dealing with this near rootless P. sanderianum seedling I received from Sam and I forgot to water it one day beforehand. The leaves became somewhat wrinkly, the bottom leaves have become droopy, and it has not grown a single root in the three months that I've had it. I've cut watering in half a month ago since I unpotted it and noticed a lack of roots and moisture in the middle of the media but I'm a bit concerned that the top of the media dries out too much for root production. Do you guys have any luck growing this in sphagnum? I find that sphagnum mixes dry more evenly but I'm a bit scared since most reports of multiflorals in sphag long term result in death. Below is an image of it a month ago when I unpotted it.
