During the day and night? Anyway, if that's you highest temp for the
day, I think your plant is feeling a bit chilly. After watching my
lowlanders for several years. (Each year I have more and the older ones
keep getting bigger and changes in humidity and temp seem to affect
the larger plants even more than the little ones...) I have noticed
that lowland Neps, like N.ampullaria and N.rafflesiana stall out in
winter. Oddly, it seems to take awhile for the lowered temps to slow
the growth of lowlanders, while too much heat quickly shows it's face
by stopping the growth of pitchers in highlanders.
