I was paging through the Nepenthes archives tonight and saw a post asking about utilizing misting as the source of humidity and one response was that frequent misting can lead to disease.
I keep my nepenthes in a 29 gallon aquarium with a lid and almost no air exchance except when i open the tank and mist every day or sometimes twice a day. pretty much the leaves always have water droplets on them. I thought this was the way to go with Nepenthes.
Well, I've noticed on my little pot of horrors "x Judith finn" plants that there are reddish brown pock and scrape-like marks on my plant (almost look like "potholes" in a road). My Ventricosa is also making new twisted leaves and also has these marks on the older leaves, the truncata, alata, x coccinea do not have the marks or "twisted" new growth.
Here's the conditions of the 29 gallon aquarium - like a 20 only a bit taller:
lighting 4x20W (80 W total flourescent light)
Lid sealed except for 1/4" hole drilled in the back - occasional use of supplemental DIY yeast CO2 (when I remember to recharge the bottle).
Should I lay off the misting?
