Hello, I have a question on my talangensis. I grow this plant for a month. And now it has grown two new leaves. But the new leaves are shorter than old leaves. And the immature pitchers are exactly the same to themselves a month ago. No sign of growing bigger. Is it normal or something wrong? The growing conditions are: Daytime temp peak: 70F; Nighttime temp peak: 54F Daytime humidity: about 70%; Nighttime humidity: 80%-90% Light: no direct sunlight. I keep it in a bright shade place. Water: distilled water This plant is pretty young. The pot size is 2.5 inch.  |

It probably needs more light. Can you give it an hour of morning or evening sun? If not then you might want to give it some artificial light.

Talangensis needs very high humidity to pitcher. It will grow fine in lower humidity but it's unlikely to pitcher.

those humidity figures seem OK to me.
If you just moved your plant to a new brighter position the leaves may get smaller and more turgid(harder) and the pitchers might initially be smaller, but it should settle in.
Nepenthes can benefit from some late afternoon or early morning direct sun. i have some plants growing in full sun all day. just make changes in small increments and see how the plant does.

I would agree for many other nepenthes that the humidity looks fine, however talangensis likes much higher humidity than most other nepenthes.

I could be and probably am wrong but it's easier to give it a little more light than it is to raise the RH(unless you live in a dungeon). I'm only growing a couple of lowlanders and have no experience with this plant so I could be way off.
manders do you grow this plant?
zhillin peter is right about not changing the environment to quickly. If you are going to give it more light then do it slowly.

Many thanks, guys. Actually, before I posted my question, I thought the light might be too bright. Now I know I was wrong. The light should increase. For humidity, let me increase it by 10% and see what happen.
Honestly, young talangensis is difficult to grow for a newer to nepenthes, like me. If other people want to grow this species, but without much experience, I suggest to choose a medium one (although costs more money).

If you are going to give it more light then do it slowly. Yes I do grow it, with around 60 other species of Nepenthes and several hybrids. I used to grow more species but I found some just didn't suit my conditions and were too difficult for me to grow, so now I stick to the ones that I find not too difficult. I found Talangensis is a very easy nepenthes to grow but hard to get it to pitcher. I had it in a greenhouse this summer in full sun and that didn't work hence i'm not convinced raising the light level will work. The only thing that has worked for me is to put it in a fish tank and raise the humidity. I also know that growers in bangkok have had to raise the humidity and bangkok is pretty humid to start with. You have to remember that the requirements of every species is subtly different and what works for one plant may not work for another... |

I know this and the only reason I suggested more light and posted the video is because Jacob doesn't mention the species in the video. If it were me and it is true that this species needs high humidity to pitcher then I would have mentioned it also. I realize there are many different species but I would have mentioned more than just the two he did if they require more humidity. A couple more seconds worth of video wouldn't matter that much. It's not that I doubt YOUR word. I take most of what I read on the internet with a grain of salt. Don't take it personal but I'm still going to ask Jacob and another good source of info on Nepenthes. |

No offence taken and your right not to take too much notice of what's put on the forums. A lot of advice that is given on these types of forums is purely speculative and even more so when given by people who don't actually grow the species in question. Personally I try to limit any advice given to the species i've actually grown and had reasonable results with. Still whatever advice is given should also be taken with caution as everybodies growing conditions are different.
Nepenthes growing in general tends to be full of urban myths that just get perpetuated year on year. Many times the only way to know for sure is to try it.

The other thing that you may want to try with talangensis, and this is speculative because i'm not 100% sure with this species, is that the pitchers may form more often if they are in contact with the ground. This is something that works with many Nepenthes, and some of my species simply wont pitcher unless the tendril is touching damp compost.

I have heard of this and one might try it, but i have not found this necessary for N.Talangensis, i have two plants that pitcher no problem. 70% daytime humidity- 90%+ at night.
Talangensis is not a particularly difficult plant. just very slow growing.

Peter, how much light are you giving them? I would love to be able to get mine to pitcher in a normal greenhouse as it would make looking after it much easier. Do you give them sunlight, if so how many hours a day? etc.
