Looking good! Seeing your N. ventricosa makes me wonder if mine's sick or something...
"The plants you grow, end up growing you."
My Grow List:
Your Sang looks great.
Although I'm not so sure that humidity has anything to do with the way the ventricosa looks, my two ventricosas are in great shape and their humidity is always low. I guess my lids don't last as long before they dry out though. Thanks for sharing.
I'm always amazed by a nice looking N. ventricosa, I've grown all sorts of "difficult" Nepenthes species but somehow I've killed every form of N. ventricosa I've tried, Lowes store plants, gift cuttings, trades, nothing they all croak. I don't know what I'm doing wrong, I've had them in warm humid LL conditions as yours are; dead, I've had them in cold humid HL conditions; dead.... I'm gonna probly give up on trying to grow N. ventricosa. LOL
I've done all the proper things, I've been growing Neps successfully since 2000 in climate controlled grow chambers (took a couple years off when life intervened and I sold my collection). I use R/O water with at least once monthly flushes with distilled. Grow in bark / moss mix or even pure live moss (currently all my highland Neps are in live moss orchid baskets but N. ventricosa didn't like it there any better than in bark/moss in the lowland tank. Seems so ridiculous but N. ventricosa is one of those I can't seem to grow even if I can grow the more exotic stuff like N. bicalcarata, N. rajah, N. hamata, etc. with no problems. Perhaps it's simply a true intermediate that needs something inbetween my Lowland or Highland grow chambers...Well it might be a problem with the growing media? Mine are in 40% Orchids(coco fiber) mix and 60% Dead sphagnum moss. Make sure not to give them too much water, also (you probably did not but) DO NOT USE tap water, at chlorine and other minerals will kill the plant, use water Equivalent to Distilled water <=10 ppm RO (reverse osmosis) Also works great
