My humidity goes from 65 to 80% at the 7am watering, and it drops to 60 by 7pm when the light goes off. I can water the mounts up to 3x day lol
When the light goes off, humidity rises back into the 70s as things cool.
This is labeled as New Zealand tree fern, and under the dame distribution as Orchiata I believe. They offer it in slab form for mounts, or shredded for potting.

It is softer than regular tree fern, and the pieces appear fine, but it maintains it's structure (air passages) when saturated.
The slabs can hold quite a bit of water if you drench them, and some plants may root into them. I purchased both Sophie's Orchids. There are also some vids of the products on youtube.
