I've noticed a tendency toward mild shell fungus with young elongateds in a closed chamber -- still working on solving that one. I would suggest going as large as possible with the enclosure, with lots of plant cover and things to climb over (rocks, logs, etc.). Mine do a surprising amount of climbing.
I dampen the orchid bark by dumping water into it. The lower layers stay damp while the upper layers wick the moisture up so it can evaporate into the closed chamber and keep humidity up, while maintaining a relatively dry surface. It can't get cold as it is in a heated closed chamber where ambient temp is maintained by a thermostat.Thank you @Tom, I switched to bark two weeks ago. I used coco coir before that. I read it here on the forum. U use it and Mark, I think. So I tought I would try the change.
Is it ok if there is a layer of water on the bodem and the bark on top of it? Doesn't it rot or gets to cold for Turt and Indu to be on?
