Hi , my name is justin and i'm new to this site. I started to grow carnivorous plants about a year ago and I have four plants. A sundew, a nepenthes, a sensitivity plant, and also a venus fly trap. I grow all of them in the same terrarium and i had a few questions. I bought my first nepenthes about 3 months ago and it's already grown 5-6 new pitchers. The only problem is that i can't seem to get them to colour nicely. They only have a little red around the perisome and the upper part of the pitcher. If someone could giveme a few tips it would be greatly appreciated.

O, and i also have the same problem with my venus fly trap to.
