This kind of a stale question since we have growers asking about growing conditions over and over again.
But please kindly bear with me 'cos I really want to grow my N. hamata, macrophylla, ephippiata etc well in typical lowland climate.
1. I have a choice of growing the plants with lights or sunlight. My climate has humidity good enough for ampullaria and bicalcarata to pitcher in a windy spot. What's the highest day temperature and lowest day humidity a typical highland is able to withstand and do well?
2. Cool nights are not possibly here until October. Until then, I need to use a wine cooler. I tried keeping the plants at 100% RH in the wine cooler but have some develop leaf rot (blackening from the tip and moving inwards). I suspect it is due to stagnant air in the wine cooler. I've read that highland neps are less fussy about a drop in humidity and I am considering growing them a little drier to prevent leaf rot. What is the lowest humidity a highland nep can take at night?
3. Why is it that I see that most growers have live sphagnum growing with their highland neps? Does that mean that besides cool temperature, the humidity is although high?
