>I have two questions directed toward Nep. growers. (1) What is the

temperature and relative humidity in your growing areas >(Tanks,
greenhouse, tables)

I am growing in an undersized greenhouse/ lath house. Winter temps :
extreme low 53 F
/11.6 C, extreme high 85 F / 29.5 C. Much below this I see cold damage
/(red edges) to
the leaves of N. gracilis, N. rafflesiana, sometimes N. bicalcarata and
N. merrilliana. N. ampullaria is tougher than most people give credit.
Relative humidity is typically 70 percent, but may drop to 50 percent or
rise to 90 percent Extended low humidity will damage existing pitchers,
especially when combined with high temps.

Summer temps: low of 80 F / 26.6 C, high of 98 F / 36.6 C. . Relative
humidity never drops below 60, and is typically around 80-90 percent.
It is too hot for most Neps, but I give them a little air circulation
and mist them 2-3 times a day when humidity drops below 70 percent. Mid
-late summer we have consistent afternoon rains that help take the edge
off the heat, and provides a nice cool watering. N. maxima, veitchii,
sanguinea are not happy at this time, but are tolerant. July thru Sept
is a real problem for me, making most highlanders impossible.

>(2) What method(s) do you use to keep the humidity high enough...

Soak the gravel floor with the hose and mist the plants with distilled water.

Hope this helps and is not too long winded.

Until later,
