So true about sulking Phals..I think it is trying to get the proper timing when to repot, but sometimes just got to repot a newly arrived one, to be sure it is not suffocating in moss or have lurking crawlers below.
There is one type of orchid I would really like try in my area..Eulophia petersii, says it thrives in arid environments, sounds perfect for our areas saecho. In time, I would venture on it..still trying to behave.
