Thanks.
Carol, I bought this Darwinara x potted like that. It seems happy so I left it alone. Silva Orchids grows them this way. After a while the roots attach to the pot anyway or grow all over the place.
I have no idea what the humidity in the greenhouse is. Remember I am able to grow Cacti & Succulents in the greenhouse too, so I don't think the humidity stays up for too long after watering.
I grow these little vandaceous Orchids very sunny, warm and flood ( water with a sprayer) the whole plant daily, since they dry up fairly quickly!
You could just try one, they don't take up much room.
