I recently got brave enough to try another heli (previous attempt had a plant going gangbusters that just gave up the ghost on me - it happens, but I felt like a bad heli grower, so opted out for a couple years). I'm keeping the new acquisition relatively humid as I started with fresh divisions. BUT, I found this video from ICPS super interesting. It suggests that (with proper acclimation) maybe humidity requirements are lower than we think. Once I get a few new pitchers under my belt, and some roots on the plants, I'm going to 'humidity wean'. As Panman said - slowly!
Here's the video:
