Hi Donald
This should be a gorgeous chid when you get it to bloom! I just LOVE mohlianum!!!
According to Orchidwiz, neither of these species call for a winter rest, growing conditions should be maintained year round.
Give it low light (the sulawesiense calls for Phal light while the mohlianum calls for a little more than that), temps in the low 80s for day and low 70s at night should work fine and they both like very high humidity, 80-90%.
because of the growth habit, it's best to mount this one but that means extra work in trying to keep those humidity rates up.
So...don't treat this one as a nobile...start watering/feeding it and you should be back on track
