90 and 98 are "cool"?
I always consider "dracula cool" as never exceed 80
Yes I agree. The figures can be misleading. Just like Vanda coerulea (which comes from much the same areas) I would not call bellatulum ''cool growing''. Yes they can get cool or even cold at night during the dormant season but look at the diurnal highs!, certainly not cool, more like warm to hot! Its very difficult to provide the huge daily swing in temps which these species have evolved with. I suspect that's one reason why the Vanda is such a difficult subject as well. If you imagine bellatulum growing on/in rocks and subjected to daily highs in the 90's, how cold does it really get down at root level? I would guess cold at the leaves but ''mild'' temps at the roots at all times. Therefore I would work on a 60F minimum for most of the time with an occasional drop to 50 but not much less and as high as you can manage during winter days???????????.......But I'm still a beginer with this species.
