Yep... this is what I shoot for with my lowii. I'm still not sure I'm getting the night time temp drop low enough.Nepenthes muluensis x lowii should be grown with daytime temps around the high 70s low 80s and nightly drops to the 50s, the lower the better. that's how i treat all my highland plants. humidity isnt that big of an issue with lowii crosses in general but if you insist, a RH of about 70% should do well. it's really more of a lighting issue when it comes to pitchers.
The photo project sounds cool!
