| Interesting idea for potting materials. I have found a different approach where the dens are grown in lava rock and then a bit of moss is layered on top keep the moisture in. The plants still have plenty of air around of the roots and there is some added humidity from the moss.
I am planning on growing these inside my house sitting on humidity trays. The location they will go is a cluster of oncidiums, brassidiums and the lone dendrobium rescue (type unknown). The temperature ranges from 68-80 right now and the humidity ranges from 50-70% according to my meter.
I am just curious as to how to hold them upright until the roots begin to move into the lava rocks. Seems foreign considering all my other orchids are in some type of bark mixture. The moss will be easy in that I can simply lift it off and add new over the course of the year.
