RJsquirrel, what vendor do you refer to? I suspect is one that also sells on ebay and has nice species but they look like they belong to a flask more than to a pot.
anyway i saves some seedlings by putting inside a jar with lid like this
SLOM Jar with lid - 17 oz - IKEA
(a bit taller) amd some sphag and chips / leca in it.
I add some peroxide to keep it free of molds.
I had a small Bulbophyllum in it that was dying and now it has new growth. I keep it sealed for days.
I have a larger one where i put a Ficus religiosa seedling and a leafless 3" broken piece of vanilla orchid and a similiar piece of Ludisia discolor and they are all growing new roots and leaves.
it could probably work with too small seedlings.
Anyway did not mean to highjack the thread. Sophronitella violacea seems great!
