Platty Posted February 12, 2013 Report Share Posted February 12, 2013 Hi everybody, I'm fairly new to growing Neps. I currently have: N. alatla N.alba N. sanguinea N. spectabilis in a terrarium. The temperature fluctuates from 20C during the day to around 13C at night and humidity is up around 99%. All has been fine over the winter and they have been producing pitchers. However recently my N. alata leaves are growing small and crinkled and no longer producing pitchers. (It has been producing lovely 4/5 inch pitcher - the last pitcher was an inch. ) My N. sanguinea lids are shrivelling quickly although they have only been opened a month. My N. spectablis is now starting to produce smaller pitchers too! The artificial light is on for 12hours Could anyone help? Should I install a small fan? Cheers Quote Link to comment Share on other sites More sharing options...
dimitar Posted February 12, 2013 Report Share Posted February 12, 2013 The artificial light is on for 12hours What light do u use and how strong is it? It would be wise to instal fan. Quote Link to comment Share on other sites More sharing options...
31drew31 Posted February 12, 2013 Report Share Posted February 12, 2013 With high humidity like that there is a chance the media is staying too wet so it may be wise to check one of the plants roots that are not looking too good. If you have a very chunky media this is probably not necessary though. Installing a fan is always a good idea. Whenever I use terrariums with a glass top, I leave a 1-3cm gap along one side to allow for air exchange. Humidity usually ranges from 70-90% depending on misting and watering.

loligo1964 Posted February 13, 2013 Report Share Posted February 13, 2013 Usually, the issue is too low a humidity; though seedlings can be adversely affected by high moisture environments. I would also encourage you to increase the photoperiod for your plants, to perhaps fifteen hours . . . Quote Link to comment Share on other sites More sharing options...
Dave Evans Posted February 13, 2013 Report Share Posted February 13, 2013 I would try to keep a max humidity of 95%. Fungus just grows too easily if the humidity stays too high for too long. Quote Link to comment Share on other sites More sharing options...
mobile Posted February 13, 2013 Report Share Posted February 13, 2013 Whilst high humidity can cause issues such as fungal growth, I suspect that there is something else at play here in regards to the crinkled leaves. Are you able to post a picture? Quote Link to comment Share on other sites More sharing options...
Dicon Posted February 13, 2013 Report Share Posted February 13, 2013 I agree with mobile, sounds more like a low humidity problem so something else is wrong, such as uptake of water? Quote Link to comment Share on other sites More sharing options...
Maiden Posted August 15, 2013 Report Share Posted August 15, 2013 (edited) Im late, again, but i think its a temp issue. Try provide warmers temps day and night. I grow all my hl neps in 95%RH, 25C/18C. Last year i tryed growing my nep sanguinea in the same temperature as you said, and the pitchers where very small. I had to move the plant in a warmer place. Of course, i talk from my experience, im not a nepenthes jedi :-D Edited August 15, 2013 by Maiden Quote Link to comment Share on other sites More sharing options...
snapperhead51 Posted August 15, 2013 Report Share Posted August 15, 2013 think a photo of the plant and its affliction would be wise , to make a better judgment on its condition and remedy . Quote Link to comment Share on other sites More sharing options...
