Proper acclimation will prevent unnecessary pitcher loss and mitigate shock from shipping damage. This rooted cutting will lose one pitcher due to shipping damage, but the other one looks great! If you can't completely seal the bag due to the size of the plant, inverting the bag like a dome works almost as well.
Rapid Bag Acclimation Procedure
After unboxing and inspecting the plant for shipping damage and pests, pot the plant up and water the media well. Fill the pitchers with water and completely seal the plants in ZipLock bags for 1-2 weeks. After I start to observe growth in the new plant, I slowly start to adjust the plant to my regular growing conditions by opening the bag up more and more every day - maybe only open halfway the first day, then opened completely but still in the bag for several days, and finally removing the bag after about a week. Bam! The new Nepenthes may still lose a pitcher or two from shipping damage, but most will hold on to their existing pitchers and start developing new ones right away 2-3 weeks of gentle acclimation. Most new plants treated this way start leaf jumping right away! I'm so happy to have found this technique and will be using it on every new tropical pitcher plant that I acquire!
