Yeah, last year i grew nepenthes with my helis, was ok, but not optimal. And the nep was not lowlanders. Your heli hybrid maybe can handle more warm temps? And maybe your nectar spoon can be bigger with better lighting? Like the one on my picture? But again, maybe im wrong, because your pitchers seems to have great colors!
But man, im not the extrem expert lol. Like a said, maybe im wrong, i have to read more about all this.
And each setup, in each country is differents ! Differents elevation and weathers etc.
I think cp4ever will need to make his own tests, and found what is the best for his setup and his plants.
If you grow your lowlanders with your helis, then you are a outstanding grower ! Maybe somebody else with less experience cannot do that.
Thanks for your replys, and making me learning
