Vandaceous orchid problems...

[Neverend]

Hello everyone, I've just joined Orchid Board, a pleasure to meet you all.

I grow mainly Phalaenopsis orchids, and am experimenting with other genus of orchids, and it seems to me that I'm horrible with vandaceous orchids.

Firstly, my Aerangis fastuosa, although growing, is not having a 'stable' root system. There's no root growth, and I worry that the root system is collapsing. Currently it's grown in a basket with loosely-packed sphagnum moss. The moss dries out sometimes but I don't think humidity is the reason why the roots are not growing.

Second, my Ascocenda Crownfox Red Delight (Ascda Peggy Foo x V denisoniana). I give it direct sunlight as it seems to be liking it, especially with some growth, unfortunately like most of my other orchids it is reluctant to bloom. I'm kinda foreign to Vanda care, so maybe anyone can help me with this?

Thanks for taking the time to read this...
