Still, stale or low air flow orchids

[harpspiel]

Orchids I have attempted in a small, sealed jar (with no fan) that have not done well:

Lepanthopsis astrophora
Lepanthes telipogoniflora
Phalaenopsis hainanensis
Bulbophyllum nipondhii
Dendrobium limpidum


I haven’t found any orchids that do well. The telipogoniflora held up the best, but I don’t feel like it was happy. Bucephalandras and Peperomia guttulata have done well in that same environment, for what it’s worth.

I suspect the orchids would have done a little better with a fan, but they would also need to have fresh air introduced occasionally. With my “jar” (it’s a tiny glass lamp base) I try to air it out once a week.
