A few weeks ago I decided to acclimate one of my favourite nepenthes in my collection (N.veitchii) in room humidity since it was fast outgrowing the hot house I had it in. Upon some research- the hairy nature of N.veitchii allows it to withstand lower humidity so I was positive I wasn't going to kill my plant. Here's my results so far:
Week 1- No change, plant continues to grow.
Week 2- Browning and yellowing of older leaves, new leaves remain in fantastic shape. 2 out of the 3 pitchers it had were drying out from the top. Good news: plant is still growing and forming a new pitcher (newest tendril is clearly swelling fast)
I'll post some pictures soon!

My veitchii seems to be doing fine in the 40-50% humidity of my grow space in the basement. It's 50% humidity after I spray and water, 40% most of the rest of the time, even as low as 30% if I leave things for a few days. The pot is in a tray of water and I let it dry out for a day or so, then refill it.

Yup, veitchii is just fine with lower humidity. You're going to have smaller pitchers and a slower growth rate compared to your grow chamber but it will be fine in the long run. I've grown several veitchii in my window and flowered them so it's entirely possible. They go outside for the summer and inside for the winter.
I've also grown most of the other intermediate species this way, maxima, vogelii, platychila, faizaliana, fusca, truncata, ect. You could probably get away with other species too but the intermediate species are nice because they don't need to hot or the cold.

My veitchii is in around 30% RH. I make sure to give it a daily mist, it seems to help with pitcher production. I'm considering of trying to acclimate a N. Jaquelinae x Izumiae to low humidity, any thoughts? It seems like a fragile species, but it would look fantastic hanging on my grow rack.

From my experiance there are a couple of things to consider for windowsill Neps. One of the biggest things I find is they have to be big enough. Ideally between 8-10 inches across, 6 inches would be the smallest I would do. I've put small plants out and they grow slowly, the larger plants adjust far faster and still continue to grow, they also deal with the temperature swings much better. You hybrid (not species ) might be able to adjust, it will have hybrid vigor to help but both parents being true highlanders will make it much harder.

My miranda continues to grow in the winter in ~25% humidity. However only pitchers that are already developing will open and they will be stunted. I mist almost every day. Not sure if it makes a difference.

I've had a miranda in my office for a year and a half and I've never done anything to try to increase humidity. I do notice it grows slower in the winter and faster in the summer, but since I've had it, it's always had at least one pitcher. I have a N. bongso on a south window sill and it's been growing very slowly the last two years. I remember seeing a site about window sill nepenthes earlier and the author seems to have pretty good success with a lot of species with room humidity.

Update on this. N.veitchii is growing fantastic in room humidity and pitchering very well. Next up: N. x unknown! Maybe even a bicalcarata eventually. My method of acclimation is this:
1: Place nepenthes in a big ziplock bag and seal it. 2: Open a small hole on the side of the bag. Enlarge this hole with your fingers every 2-3 days until the hole makes the ziplock bag useless. 3: Remove nepenthes from the bag and place/hang it at the spot you wish to grow it. VERY IMPORTANT: Mist the plant as often as possible for the next week or two. It's inevitable that the plant will sulk and a few leaves will die but as long as it pulls though, it should grow well in the new environment.

What is the humidity? In my house it is ~20% in the winter.

What is the humidity? In my house it is ~20% in the winter. My house is ~20% in the winter as well. In the summer, it varies. It may be ~50% on a humid day and ~30% on a regular day.

OK I have to try this in the fall.

Humidity is a very important part of the nep's growing habit , but will depend on where in the world you live too , here low humidity is small pitchers low/slow growth and often plants dying, the amount of sun or strength of sun and over all temps will be a factor as well , many plants will adapt as well. Over all the humidity will increase your plants pitcher size and general heath of the plant , ,as a rule ! lowering the humidity can affect the plant over all growth and health long term.
from my experience in the wild and here ,the best humidity to grow neps with is around 60 to 70 % RH . will depend on you plant ,if it's H/L, inter or LL of cause.
because we can get all most zero humidity in the very hot dry days in summer at 40 to 47 c here its most important to have some form of humidity here it can be quite difficult at times , as humidity is what help's protect the leafs from drying out from direct or indirect sunlight and burning and causing, black rot , stem die back , and leaf burn , all leading back to death of the plant if not treat in a proper manner for plant re-health, most neps can be treated by many procedures to stop them from dying if treated in a proper manner,or knowing what to do .

John Agreed, however for those who do not own a greenhouse, the only way we can grow large nepenthes is getting them to tolerate less suitable conditions. It also really depends on the species/or hybrid. Nepenthes with think and plentiful trichomes tend to do much better than smoother nepenthes since the hairs reduce water loss, and slightly increase humidity around the plant. Also certain hybrids such as xVentrata do fantastic in lower humidity conditions thanks to their hybrid vigor. Not every nepenthes can tolerate lower humidity equally as well as another, but you never know. There might be slight variations between individuals, some might be more tolerant and others not so much. I've had my veitchii growing in low humidity and it has huge leaf jumps. I definitely puts slightly smaller pitchers compared to the ones that it was setting in my grow chamber, but overall, I wouldn't say it is declining in any way.

John That's what happened to most of my neps inside my terrarium, when the temp gets too hot they all dying from black rot and stem die back. Even though the humidity is around 70-80%.
