Hi, thanks for your kind replies.
My Catts are kept in a big orchidarium, under a 200 W MH light.
R.H. is usually 65-80%
They are mounted on cork slabs and their roots look fine.
I water them only by daily
misting and i never soak them (I think it should be enough for orchids that live in a wardian case with high R. H..or not???)
Do you think I should mist them more often?
