Yes I think they have no troubles with warm summers and very cool winters, but I think if you get them up in the 90's they need very good airflow and high humidity. And provide more shade when it is hot if you are growing in a greenhouse.I grow them in Ha Noi, they spent a very warm summer without damage. In fact fairrieanum need a cool season during winter, but in summer it can be extremely warm in the wild.
Mine has been in s/h for over a year and has grown very slooooow. But, my temps are probably too high for it's liking which may be the cause for that.So do many of you use S/H culture for it
