White hairlike fuzz (it's not mealybugs) on den canes

Hot? Definitely warm, but I know that mine gets night temps down to 60 deg F or so. And days are whatever the "greenhouse effect" produces, so lately days have been maybe 70 or a bit over but not by a lot. And it grows and blooms for me. I'd think Phalaenopsis temperatures (but more light) would work well. (Mine doesn't get all that much light either because my GH is fairly dark, it seems to do fine)
