Yes, our lousy humidity levels plus the drought here in Cali makes it harder to grow a lot of plants. I am only growing that Vanda since I know it can take our mild winters easily, so I can leave it outdoors even in winter. Some have been using a set-up called vase culture. I still have to read further, they did have examples using a Vanda.
I saw Eulophia petersii at a succulent nursery in Berkeley one time, I was excited to see it..but have to turn away..they are selling it for $75...no way will I buy that expensive. I just bought other succulents instead
If there is one orchid alliance that I really find easy, it is those under the Oncidium alliance. Though always thirsty..good for those who tend to overwater.
The only thing I do not like, their leaves easily get those dark spots, makes you panic if it is bacterial already..but it does not hamper the plant from blooming. Just makes the leaves a bit ugly looking at times.
