As a side note about the fertilizer spray, D.trinervia seems to be
particularly sensitive to it - within a few hours of being sprayed
all of the leaves fold up or over as if they had captured a bug
and stay that way for 24 - 48 hours. It seems to be happy with it
though because it's producing leaves rapidly and looks very healthy.
Unfortunately, it's one of the few that is not blooming.
(In case you're wondering, the plants are all blooming because they
think it's spring / summer - the terrarium is heated by 4 x 40 watt
bulbs which are on 16 hours a day (mostly at night)...daytime (their
night) temps are about 45 and nighttime (their day) temps are
65-75) - this is in an otherwise unheated garage).
