Dendrophylax lindenii Winter Rest Care

[Shadeflower]

Is that the plant in a completely sealed jar?

I've never grown ghosts but that seems dangerous. The cork is organic material.

I'd have the lid open. The Jar is pretty tall so will still maintain a decent humidity.

I have tried with many orchids in a completely sealed jar and it does not work long term.

What works better is having a layer of pumice or lecca at the bottom of the jar. Keep that moist all the time. Place the cork mount on top and keep the lid open.

The pumice should keep hydrated for about a week so humidity will stay just as high for that time but the open lid will allow for a little air exchange.
