I was just given some bench space in the horticulture club greenhouse at my university. I live in a tiny apartment, so I'm excited to finally have room to grow Nepenthes. Light and humidity seem perfect, but according to the greenhouse complex manager, the hort club greenhouse is heated to a constant 70f. In practice, I think that the greenhouse experiences a slight drop in temperature at night, because I seriously doubt that it is s perfectly insulated (I live in a very cold climate). I think that I will be dealing with a day temp of 70-75f, and a night temp of ~65f. These conditions obviously limit what I can grow, since the day temps are too cool for most lowland varieties and the night temps are too high for most highland varieties.
I've been looking over the some Nepenthes varieties offered currently by online retailers, and I am interested in the following.
N. sumatrana (Don't know much about this species, but I have heard that it is tolerant of cooler conditions than most lowlanders)
N. ventricosa x arisolochioides (have heard it grows well in both lowland and highland conditions, like the parent N. ventricosa)
N. spectabilis x aristolochioides (no idea)
N. truncata x merrilliana (have heard from growers that this cross grows well under a wide range of conditions)
Are these good choices for my conditions? Does anyone here have experience with these species/crosses?
