Cultivation Ease:
Super incredibly VERY easy (for a nep).
Watering:
3 times a week with purified/bottled/RO/not sink/not hose water should do fine, just keep the soil wet.
Humidity:
50-100% is optimum. This plant does amazing in windowsills and as a house plant (near window). Over time might do well outdoors year round (we've never tried this)
Light:
at least 60% (more accepted over time)
Temp:
60-85 is optimum. Ours have withstood 130 with 10% humidity for a few days, but this is very dangerous to the plant. Try to supply a temperature drop at night.
Natural Range:
As with all other neps, N. ventricosa is native to the Indo-Pacific area of our great world. More specifically it is native to the Philippines. Grown as early as the Victorian Era, N. Ventricosa is often overlooked as a common “mutt” of nepenthes. This is far from the truth! With new bigger, easier (if that's possible!), and more colorful cultivars coming out, hopefully this prejudice will be overcome.
