Those pitcher plants look amazing! I have always wanted to do something like that... You may have just inspired me to jump on it.
How do you keep the humidity high enough to keep the plants from drying up?
And at what temperature do you keep all this at?
They do need a winter rest. We put ours in the fridge for about three months,in plastic bags. After that you need to repot and cut them down.
I really recommend this book if your interested in carnivorous plants. http://www.californiacarnivores.com/...tographed.aspx
